1954rif. 2832Princeton NJ: np 1954. First edition. nb. Fine. EXTREMELY RARE AND BEAUTIFUL SIGNED PHOTOGRAPH OF EINSTEIN BY FREDERICK PLAUT. SIGNED ON THE IMAGE BY EINSTEIN: "A. Einstein 54". A fine photograph of Einstein in 1954 a year before his death sitting in his Princeton home surrounded by books and holding his pipe gazing slightly away from the camera. In his 1964 collection of photographs The Unguarded Moment the photographer Frederick Plaut explains the circumstances of his evocative photo of the elderly Einstein: "There must be a moment in every professional photographer's life when he is so in awe of his subject that he can scarcely focus his camera. That moment for me was when I met Albert Einstein at his home in Princeton. Certainly the great man was not formidable; he greeted my wife and me graciously and proceeded to chat with her while I went to work. I remember that she asked him about his music and when he told her that he no longer played his violin she murmured 'That's too bad.' He smiled 'Ah no. It would have been too bad if I went on.' In the final moments of our visit Einstein looked at me very seriously. 'I hope' he said 'you can sell these pictures for a good price.' Astounded I blurted out: 'Oh no Sir. I have nothing to sell. I just wanted to photograph you.' His face clouded. 'Not sell them If I had known that I never would have let you take them.' After we left I realized the significant of a delightful remark attributed to Mrs. Einstein. Someone once asked Mrs. Einstein whether she understood Professor Einstein's theory of relativity. She answered without hesitation 'No but I understand Professor Einstein'" Frederick Plaut The Unguarded Moment A Photographic Interpretation. The photographer Frederick Plaut moved to the United States from Europe in 1940. After being "discovered" by the legendary photographer Edward Steichen Plaut soon was invited to exhibit in numerous exhibitions. "At the Museum of Modern Art his photographs have been shown in many exhibitions including: 'The Family of Man' 'Music and Musicians' 'The Exact Instant' and others. Plaut's work has appeared in Time Life Esquire Look Saturday Review Vogue U.S. Camera Modern and Popular Photography andRealities et al" The Unguarded Moment. Provenance: Acquired directly from the family of the original recipient Arthur Klein with the original mailing envelope stamped "Jan 27 '54" from The Institute for Advanced Study in Princeton where Einstein was working at the time. Arthur Klein is primarily known for founding with his wife Luce Spoken Arts a highly influential company formed in the 1950s that created and distributed recordings of the works of famous writers and artists usually reading from their own works. Princeton NJ: 1954. Silver gelatin print approximately 4.75 x 6.75 inches. With Plaut's studio stamp on verso. Fine condition with Einstein signature - nicely centered at the base of the photograph - particularly strong. As Plaut mentioned in his account of the photographic session he never intended to sell this photograph and it is likely very few of these photos were printed and distributed. EXTREMELY RARE: WE CAN FIND NO OTHER EXAMPLE OF THIS PHOTOGRAPH SIGNED BY EINSTEIN. np unknown
1931rif. 4675JHollywood 1931. An unusually large image 11” x 14” taken on January 8 1931 when Einstein and his wife visited Hollywood. The image shows Albert Einstein and Film Mogul Carl Laemmle Senior Founder of Universal Pictures. The photograph is a striking informal image of these two noted Jewish leaders and fellow German emigres chatting on a studio sound stage at Universal City with Mrs. Einstein visible in the background. The photograph is inscribed and signed by Albert Einstein to the head of Universal’s publicity department John LeRoy Johnston who had sent this photograph of Einstein with his boss Laemmle to Einstein to sign. Einstein has written in white ink: “Fur Kohn Johnston - Albert Einstein”. Tipped to the verso is a typed note written in German from Johnston on his printed Universal Pictures stationery to Professor Einstein asking him to inscribe the photograph. Many photograph portraits of Einstein are rather stuffy affairs and a number look like police lineups when he appeared in public and met famous people and dignitaries. This is a striking image of the two men conversing. A historic and excellent photograph and the finest piece from his visit to Hollywood to ever appear on the market. unknown books
1941rif. 2142520/12/1941. Brigitte Kaufmann was born in Germany but when the Nazis came to power in 1933 she fled to Paris. In France Kaufmann worked as an actress under the name of Brigitte Châtel and translated documents. She met her future husband Alfred Alexander-Katz in Paris and they married in 1939; the following day her husband was taken to an internment camp. He was given the choice of being interned in a labor camp or joining the Foreign Legion and chose the latter. Alexander was then sent to Clermont in Vichy France and the family relocated there. Dr. Walter Rudlin was a social science professor at Sarah Lawrence College in New York and actively involved in anti-fascist activities. He was the author of “The Growth of Fascism in Great Britain”. In September 1942 he left his position and joined the U.S. Board of Economic Welfare whose chair was Vice President Henry Wallace. His wife Eryl was interested in bringing Jews in Europe out of harm’s way and she knew the Alexander-Katz family. So Eryl sought to get Brigitte and her family safely out of Europe to Mexico and sought Einstein’s help. On March 12 1941 Einstein responded noting that Brigitte is his relative. “Thank you very much for your letter of March 11th. I am very gratified indeed to learn that our mutual friends Fred and Brigitte Alexander-Katz have some prospect to receive a visa into Mexico. I am certainly willing to vouch for their reliability and integrity both personal and political. I have known Mrs. Brigitte Alexander-Katz - whose family is related to mine - since she was a little girl. Her husband a very able engineer will certainly be useful to any country which receives him. If you will send me the address of the proper Mexican authority I shall gladly send any letter of recommendation desired.” This was a warm letter indeed expressing true concern and friendship for the Alexander-Katz family. On April 3 1941 Einstein again wrote Rudlin noting “Enclosed I am sending you the requested letters in the hope that they may be successful.” But there were delays and no visa so Rudlin wrote Einstein seven months later asking him to take the matter up with the Mexican government. Typed letter signed on his blind-embossed letterhead Princeton December 20 1941 to Mrs. Eryl Rudlin saying that he expects the visa to be granted but does not feel he ought to approach the Mexican government directly. “The Mexican authorities know that I am interested in the case of the Alexander-Katz family; they have kept me informed about the whole development of the matter. I have no doubt that admission to Mexico will be granted as it has been granted to hundreds of people in the same situation. I can give Mr. Alexander-Katz a recommendation but it is out of the question that I ask the Minister of Education to send him an official invitation. I have already done what could be done without intrusion.” Despite what he writes here to calm Mrs. Rudlin Einstein might have exerted some gentle pressure on Mexico by contacting the Mexican ambassador to the U.S. Gilberto Bosques; or the Alexander-Katz visas may have already being granted at that moment. The Einstein Archives is silent on this subject. But soon after Einstein soon wrote this letter in 1942 a telegram to the young Alexander-Katz family arrived stating that Einstein and Rudolph Uhlman a lawyer in New York had secured visas through Ambassador Bosques for them to escape to Veracruz Mexico aboard the ship San Thomé. In Mexico Brigitte she became a noted author actress director and translator. She became the first woman in Mexico to produce and direct television programs. Speaking five languages she also worked as a translator for UNESCO and Amnesty International. Her daughter Susana and granddaughter Sophie also became actors. unknown

1910rif. 83637Zurich Zurich 1910. Fine. Einstein writes to a friend who introduced him to Carl Jung Zurich Zurich 21 juin 1910 9 x 14 cm une carte postale Autograph postcard signed by Albert Einstein to Ludwig Hopf. 18 lines written verso and recto address also in Einstein's handwriting. Postmarked June 21 1910. Published in The Collected Papers of Albert Einstein Volume 5: The Swiss Years: Correspondence 1902-1914 Princeton University Press 1993 n°218 p. 242. An exceptional and highly aesthetic card from Albert Einstein to ""the friend of the greatest geniuses of his time"" - according to Schrödinger - mathematician and physicist Ludwig Hopf who introduced Einstein to another 20th-century genius: Carl Jung. The master invites his pupil Hopf to a dinner party whose guests include scientist Max Abraham future great rival during Einstein's Zurich years and a fervent opponent of his theory of relativity. The recipient Ludwig Hopf joined Einstein in 1910 as an assistant and student at his physics and kinetic theory seminars at the University of Zürich. They signed two fundamental papers on the statistical aspects of radiation and gave their names to the ""Einstein-Hopf"" velocity-dependent drag force. Their letter exchanges retrace the complex path of Einstein's work on relativity and gravitation bearing witness to their great complicity and Hopf's invaluable contribution to the Master's research. A few months after writing the postcard Hopf even found an error in Einstein's calculations of the derivatives of certain velocity components which Einstein corrected in a paper the following year. They also formed a musical duo Hopf accompanied on the piano the Master's violin performing pieces by great musical geniuses like Bach and Mozart. With this card Einstein invited his pupil and friend Hopf to dinner with Max Abraham at the dawn of a major scientific controversy that would pit them against each other from 1911 onwards. Abraham's theory of special relativity failed to convince Einstein who criticized its lack of observational verification and its failure to predict the gravitational curvature of light. In 1912 their dispute became public through scientific articles. Abraham never acknowledged the validity of Einstein's theory. During their brilliant artistic and intellectual exchanges Hopf undoubtedly succeeded where Freud had failed as he declared to him in a letter: ""I shall break with you if you boast of having converted Einstein to psychoanalysis. A long conversation I had with him a few years ago showed me that analysis was as hermetic to him as the theory of relativity can be to me"" Vienna September 27 1931. As a fervent supporter of psychoanalysis Hopf is known to have introduced the famous psychoanalyst Carl Jung to Einstein. Hopf and his teacher both left for Prague's Karl-Ferdinand University in 1911 where they met writer Franz Kafka and his friend Max Brod in Madame Fanta's salon. With the rise of the Nazi regime the fates of the two theoreticians were plagued by persecution and exile. Einstein first took refuge in Belgium Hopf in Great Britain after his dismissal in 1934 from the University of Aachen because of his Jewish origins. They continued their prolific correspondence in the midst of the turmoil Einstein suggesting to Hopf the opening of a university abroad for exiled German students. Hopf died shortly after his appointment as chair of Mathematics studies at Trinity College Dublin in July 1939. A precious invitation from the great physicist to one of the final dinner gatherings of the ""old school"" of science embodied by Max Abraham on the eve of the publication of the theory of general relativity which would overturn classical conceptions of space and time and propel Science into the 20th century. unknown

1950rif. 2131Princeton: np 1950. First edition. Very Good. EINSTEIN RESPONDS TO A STUDENT EXPLAINING A CENTRAL TENET OF RELATIVITY. The schoolboy David Cumberland had answered a test question saying that vertical lines are parallel; his answer however was marked as incorrect by his teacher on the grounds that the lines would converge at the earth's center. After Cumberland insisted he was correct the teacher made a deal with him: if he could find an authority that would support his claim his grade would be changed. Cumberland apparently quite an enterprising young student wrote to Einstein asking if vertical lines are indeed parallel and Einstein in the present letter responded using relativity theory to provide support for the student's test answer: October 28 1950 Mr. David Cumberland 924 S.E. 2nd Str. Fort Lauderdale FL Dear Sir: The concept "vertical" has meaning only with respect to the earth and cannot be used beyond that context. But there is the other concept lines vertical to an euclidian plane. Those lines are parallel. Sincerely yours signed A. Einstein Albert Einstein. One of the central components of relativity is that our understanding of space and time is subject to the relevant frame of reference. In this letter Einstein uses relativity - namely a shift in the frame of reference - to prove that boy's answer can be interpreted to be correct. Upon showing his teacher Einstein's letter the boy's grade was indeed raised. One 8.5x11 inch sheet of Institute for Advanced Study letterhead. Usual folds; some water spots to page not affecting text. A WONDERFUL LETTER SHOWING A VERY HUMAN SIDE OF EINSTEIN AND EXPLAINING A BASIC CONCEPT OF RELATIVITY. np unknown books

1949rif. 32820623Original brown cloth top edge gilt publisher's slipcase. Very fine with the fragile slipcase in excellent condition. A superb copy. FIRST EDITION. One of 760 numbered copies signed and dated by Einstein. This important volume contains Einstein's autobiography specially written for the book a bibliography of his works twenty-five scientists' discussions of Einstein's work and achievements with Einstein's replies. Contributors of essays include Niels Bohr Max Born Wolfgang Pauli and Kurt Godel. I. I. Rabi's review in Science hailed this as a "most important and significant volume. It is most difficult to get scientists to write simply and clearly about the fundamentals of their science and the leading philosophical ideas that guide them. … In this book there is played out a great scientific drama of the last two decades. … The book starts with an intellectual autobiography by Einstein himself. He satirically calls it his obituary. I know of no other to compare with it. Neither Newton nor Maxwell nor any of the other great giants of physics had his Schilpp the editor to catalyze such an effort. After reading Einstein's article one realizes the great loss this is to scientific culture" Science 21 April 1950.

1934rif. 1478Princeton: np 1934. 1st Edition. No Binding. Very Good. AN IMPORTANT SIGNED LETTER in English by Einstein revealing his reservations of associating with communism even in the fight against fascism. Written from Princeton NJ to Professor Albert Sprague Coolidge of Harvard University and dated February 16 1934 the letter reads: My dear Professor Coolidge: I had an opportunity of meeting personally Lord Marley and has sic very favorably impressed by his personality. It became known to me that he sympathizes with the Russian Government i.g. with the Russian communist party and that the committee for which he is active is influenced by communists. The problem as to the attitude which is advisable to be taken towards this committee is rather complicated. On the one hand the world-wide danger of fascism makes it necessary that all enemies of fascism cooperate; on the other hand an action which has communist leanings might endanger that fight since the important task undertaken in defense of culture and civilization may be linked up with interests of a political party. I myself have severed my connections with the committee which with my permission had used my name up to the end of last year. It seems to me advisable to take an attitude as follows: to help their action against fascism but not to identify oneself with the committee. Very truly yours signed A. Einstein P.S. I wish you would be good enough to use this strictly confidentially. In 1934 Lord Baron Marley Dudley Leigh Aman toured the United States to raise funds for his association the World Committee for the Victims of German Fascism. Marley through his committee was "passionately advocating a scheme for which he was to become an international figurehead - resettlement of oppressed German and Polish Jews in the Jewish Autonomous Region" in Siberia. He published a book "The Brown Book of the Hitler Terror and the Burning of the Reichstag sponsored by the World Committee and with an Introduction written by Lord Marley himself which was the first popular exposé of what was happening in Hitler's Germany. It documented the destruction of political parties trade unions and universities book-burning and the building of concentration camps. "At a fundraising dinner held in his honour in New York in February 1934 where Einstein presumably met him just before writing this letter Marley opened the Brown Book and 'speaking quietly declaring that he did not intend to harrow' read aloud to his audience of 600 American Jews some of the collected evidence of Nazi repressions. Here were documentary records of what was happening in Germany - a substantiation of the brutality that hitherto had had no distinct form in the mind of the American Jewish public. What before had been the subject of a growing fear mingled with disbelief was now being presented as hard fact and supported with detailed evidence. The New York Times 8 February 2005 reports the audience being 'startled' by the disclosures and the night ending with $3500 raised for the World Committee" The Jewish Quarterly No. 198. Einstein was correct to be suspicious of Marley's activities for it was later determined that the "World Committee" was indeed a Communist front; Einstein writing here to Coolidge in 1934 was prescient about the motives of the committee. This letter in addition to underscoring Einstein's passionate stance against fascism is particularly important as documentary evidence of Einstein's caution about having any dealings with communism especially considering that the U.S. FBI worried about Einstein's political leanings kept a file on Einstein that grew to 1427 pages.

1922rif. Bergson2EINSTEIN BERGSON Henri 1859-1941 Autograph letter signed " Henri Bergson " to Jean Becquerel Paris 24 September 1922 16 pages in-8° with envelope Some typographic pencil notes A highly significant letter on the issues and interpretation of the theory of relativity This intervention of the philosopher continues up to this day to create multiple controversies We transcribe here only a few fragments of this letter which although known in its substance has remained unpublished to this day " Monsieur et cher collègue J'ai bien tardé à répondre à la lettre si intéressante et si importante que vous avez bien voulu m'adresser. C'est qu'elle est allée me chercher de divers côtés et m'a atteint en Suisse à un moment où j'étais pris à Genève par le travail de " Coopération intellectuelle " qui nous avait été confié par la Société des nations. Me voici de retour à Paris ; je profite de mes premiers instants de liberté pour vous écrire. Le passage essentiel de votre lettre est naturellement celui qui concerne le voyage en boulet. Laissez-moi reprendre ce que j'ai dit dans mon livre Durée et simultanéité paru à l'été 1922 en y joignant quelques explications complémentaires. Il y a d'abord deux remarques importantes à faire. 1° Si l'on se place en dehors de la Théorie de la Relativité on conçoit un mouvement absolu et par là même une immobilité absolue ; il y aura dans l'univers des systèmes réellement immobiles. Mais si l'on pose que tout mouvement est relatif que devient l'immobilité Ce sera l'état du système de référence je veux dire du système où le physicien se suppose placé à l'intérieur duquel il se voit prenant des mesures et auquel il rapporte tous les points de l'univers. … 2° Si l'on se place en dehors de la Théorie de la Relativité on conçoit très bien un personnage Pierre absolument immobile au point A à côté d'un canon absolument immobile ; on conçoit aussi un personnage Paul intérieur à un boulet qui est lancé loin de Pierre se mouvant en ligne droite d'un mouvement uniforme absolu vers le point B et revenant ensuite en ligne droite et d'un mouvement uniforme absolu encore au point A. Mais du point de vue de la Théorie de la Relativité il n'y a plus de mouvement absolu ni d'immobilité absolue … Paul une fois lancé dans l'espace n'est plus qu'une représentation de l'esprit une image — ce que j'ai appelé un " fantôme " ou encore une " marionnette vide ". C'est ce Paul en route ni vivant ni conscient n'existant plus que comme image qui est dans un Temps plus lent que celui de Pierre. … Le Paul qui sort du boulet au retour du voyage le Paul qui fait de nouveau partie alors du système de Pierre est quelque chose comme un personnage qui sortirait en chair et en os de la toile où il était représenté en peinture : c'était à la peinture et non pas au personnage c'était à Paul référé et non pas à Paul référant que s'appliquaient les raisonnements et les calculs de Pierre pendant que Paul était en voyage. … Je ne voudrais pas clore sans saisir l'occasion qui s'offre à moi de vous dire combien m'a intéressé et instruit votre beau livre sur " Le principe de relativité " et la " Théorie de la gravitation " – livre indispensable à tous ceux qui ont le souci d'approfondir la théorie d'Einstein. Veuillez Monsieur et cher collègue agréer l'expression de mes sentiments les plus distingués et dévoués H. Bergson " In publishing Durée et simultanéité published by Alcan in the summer of 1922 Bergson was taking a risk that he probably did not measure himself. The purpose of this essay was to discuss the philosophical issues of the theory of relativity. The criticism of his scientific colleagues was not long in coming. Those of Einstein in the first place deploring the "blunders" or "dumplings" of the philosopher. In France it was Jean Becquerel who opened fire with a letter addressed directly to the author and of which this document constitutes the reply. At the time Becquerel held a chair of applied physics at the Museum of Natural History. He wrote a textbook entitled Le Principe de relativité et la théorie de la gravitation Gauthier-Villars 1922 which made him one of the first introducers of Einsteinian theory in the French context. Two sources give an idea of the content of Becrerel's letter: his article published the following year "Critique de l'ouvrage durée et Simultaneity de M. Bergson" Bulletin scientifique des étudiants de Paris 10 2 March-April 1923 and the extract given by Bergson himself in the first of three appendices added to the 1923 edition of Durée et simultanéité – appendix which also contains with a few lines the entirety of his answer. Bergson then chose to preserve the anonymity of his correspondent in order to avoid giving the impression of a "polemic" according to the interview of December 30 1923 with Jacques Chevalier. He merely evokes "a letter very interesting which was addressed to us by a most distinguished physicist." The discussion crystallizes on a specific point: the interpretation of the slowdown of moving clocks predicted by the theory. The famous "twin paradox" attributed to Paul Langevin provides a pictorial version of the problem as part of a Jules Verne-style narrative: an astronaut here "Paul" embarked on a "ball journey" would find himself on his return younger than his twin brother who remained on Earth here "Pierre" as if time had passed less quickly for him! In his letter Becquerel insists on the fact that the theory of relativity speaks of time actually measured on both sides by observers in relative motion. Bergson repeats by clarifying it the argument developed in his book namely that the differences relate less to real times than to fictitious times that is to say times attributed to other observers who acquire at the same time the status of simple images or "ghosts". Thus the "dilation" of durations associated with the slowing down of moving clocks is only a "perspective effect". Bergson is led to this conclusion by a strict interpretation of the principle of relativity: between two observers in relative motion there is a "perfect symmetry" each can consider itself motionless or mobile with respect to the other. Multiple empirical confirmations have since objectively proved the philosopher wrong but the question of the status of time in relativity as well as that of the relevance of the arguments exchanged continues to fuel contemporary philosophical debates. In that sense that letter constitutes a key part of the case. We thank Mr. Elie During for the information he kindly communicated to us

1930rif. 90431New York: Albert & Charles Boni 1930. First edition of this Einstein biography written by Rudolf Kayser a German literary historian and husband to Albert Einstein's stepdaughter Ilse under the pseudonym Anton Reiser. Octavo original cloth frontispiece of Einstein. Inscribed by Albert Einstein with an original poem on the front free endpaper in German which translates as "It is a curious fate to be objectified alive. Think with humor while reading. A. Einstein." From the library of Alexandre and Catherine Barjansky with her ownership signature to the verso of the front panel and notation below Einstein's inscription "S.S. 'Belgenland' New-York 14/XII/30." Russian sculptress Catherine Barjansky her celebrated cellist husband and Einstein were all close friends of King Albert I and Queen Elisabeth of Belgium. Barjansky described her experiences creating the now famed and very intimate sculptural portraits of Elizabeth and Albert in her 1947 joint memoir with her husband Portraits with Backgrounds. Catherine had an international career living at times in Rome Berlin New York Vienna Paris and Brussels. Einstein was in New York at the time he inscribed the present volume having arrived aboard the Belgenland three days earlier. Einstein travelled aboard the Belgenland several times. He was on the ship in March 1933 intending to return home to Germany when he learned the alarming news that the Nazis had ransacked his summer cottage in Caputh. He soon decided it was too dangerous to return to Germany and when the ship docked in Antwerp Belgium he immediately reported to the German consulate in Brussels where he turned in his German passport and renounced his citizenship. Einstein returned to America in October beginning a new life as a member of the faculty of Princeton University's Institute for Advanced Study. In near fine condition. A complex and desirable association. Albert Einstein developed the general theory of relativity one of the two pillars of modern physics alongside quantum mechanics. Einstein's work is also known for its influence on the philosophy of science. Einstein is best known in popular culture for his mass-energy equivalence formula E = mc2 which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics for his "services to theoretical physics" in particular his discovery of the law of the photoelectric effect a pivotal step in the evolution of quantum theory David Bodanis.

1918rif. 2839London: Fleetway Press 1918. FIRST EDITION. Original wrappers. Fine. THE FIRST INTRODUCTION OF EINSTEIN'S GENERAL RELATIVITY TO THE ENGLISH-SPEAKING WORLD. The groundbreaking first edition 1918 with the second edition 1920 containing the account of Eddington's 1919 expedition proving Einstein's theory both in original wrappers. "Einstein's discovery of the General Theory of Relativity was communicated to the Berlin Academy of Sciences in 1915. Because of the First World War direct communication with physicists in Germany was not possible but the papers were forwarded to Eddington who was then Secretary of the Royal Astronomical Society by Willem de Sitter a personal friend of Eddington's in neutral Holland. The theory is of considerable mathematical complexity but as Einstein stated in the last paragraph of his paper 'scarcely anyone who has fully understood this theory can escape from its magic'. Eddington was the ideal expositor of these ideas in English and within 2 years had written his Report on the Relativity Theory of Gravitation for the Physical Society of London" Malcolm Longair "Bending Space-time". The second edition is notable for containing a new preface that discusses the results of the "eclipse expedition" led by Eddington that verified General Relativity and catapulted Einstein into world-wide fame. This preface precedes Eddington's full report in the Philosophical Transactions.

1908rif. 2507Leipzig: S. Hirzel 1908. First edition. original wrappers. Very Good. THE BIRTH OF GENERAL RELATIVITY: FIRST PRINTING IN RARE ORIGINAL WRAPPERS OF ONE ONE EINSTEIN'S MOST IMPORTANT PAPERS; containing the beginning of general relativity the derivations of the equivalence principle gravitational redshift and the gravitational bending of light. "Einstein's road to general relativity began in November 1907 when he was struggling against a deadline to finish an article for a science yearbook explaining his special theory of relativity. Two limitations of that theory still bothered him: it applied only to uniform constant-velocity motion. and it did not incorporate Newton's theory of gravity. "'I was sitting in a chair in the patent office at Bern when all of a sudden a thought occurred to me' he recalled. 'If a person falls freely he will not feel his own weight.' That realization which 'startled' him launched him on an arduous eight-year effort to generalize his special theory of relativity and 'impelled me toward a theory of gravitation.' Later he would call it 'the happiest though in my life.' "The tale of the falling man has become an iconic one and in some accounts it actually involves a painter who fell from the roof of an apartment building near the patent office. Einstein refined his thought experiment so that the falling man was in an enclosed chamber such as an elevator in free fall above the earth. In this falling chamber at least until it crashed the man would feel weightless. Any objects he emptied from his pocket and let loose would float alongside him. "Looking at it another way Einstein imagined a man in an enclosed chamber floating in deep space 'far removed from stars and other appreciable masses.' He would experience the same perceptions of weightlessness. 'Gravitation naturally does not exist for this observer. He must fasten himself with strings to the floor otherwise the slightest impact against the floor will cause him to rise slowly towards the ceiling.' "Then Einstein imagined that a rope was hooked onto the roof of the chamber and pulled up with a constant force. 'The chamber together with the observer then begin to move "upwards" with a uniformly accelerated motion.' The man inside will feel himself pressed to the floor. 'He is then standing in the chest in exactly the same way as anyone stands in a room of a house on our earth. The man in the chamber will come to the conclusion that he and the chest are in a gravitational field. Just then however he discovers the hook in the middle of the lid of the chest and the rope which is attached to it and he consequently comes to the conclusion that the chamber is suspended at rest in the gravitational field.' Einstein observed that inertial mass always equals gravitational mass and through his thought experiments concluded that "From this correspondence it follows that it is impossible to discover by experiment whether a given system of coordinates is accelerated or whether. the observed effects are due to a gravitational field." "Einstein called this 'the equivalence principle.' The local effects of gravity and of acceleration are equivalent. "In 1907 working against the deadline imposed by the Yearbook of Radioactivity and Electronics Einstein tacked on a fifth section to his article on relativity that sketched out his new ideas. He also came up with many predictions that could be tested including that light should be bent by gravity and that the wavelength of light emitted from a source with a large mass such as the sun should increase slightly in what has become known as the gravitational redshift. "It would take Einstein another eight years until November 1915 to work out the fundamentals of this theory and find the math to express it. Then it would take another four years before the most vivid of his predictions the extent to which gravity would bend light was verified by dramatic observations. But at least Einstein now had a vision one that started him on the road toward one of the most elegant and impressive achievements in the history of physics: the general theory of relativity" Isaacson Einstein 145-49. Weil in his bibliography also notes that "On p.443 are probably the first explicit statements both of the equivalence of inertial and gravitational mass and of the equation for mass in terms of energy now regarded as the theoretical basis for the release of atomic energy." Weil 21. Although Einstein submitted the paper on 4 December 1907 it wasn't published until the January 22 issue of the Jarbuch.

1930rif. 138499New York: Albert & Charles Boni 1930. First edition of this Einstein biography written by Rudolf Kayser a German literary historian and husband to Albert Einstein's stepdaughter Ilse under the pseudonym Anton Reiser. Octavo original cloth frontispiece of Einstein. Signed and dated by Einstein in the year of publication on the front free endpaper "Albert Einstein 1930." Near fine in a very good dust jacket. Rare signed and in the original dust jacket. Albert Einstein developed the general theory of relativity one of the two pillars of modern physics alongside quantum mechanics. Einstein's work is also known for its influence on the philosophy of science. Einstein is best known in popular culture for his mass–energy equivalence formula E = mc2 which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics for his "services to theoretical physics" in particular his discovery of the law of the photoelectric effect a pivotal step in the evolution of quantum theory David Bodanis.
