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.

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.

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 books
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.

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.

rif. 225685/5/33. Germany as an island of intellectuals is no longer possible he writes blaming the fall of his country and exile of his colleagues on poor education a vestige of Bismarck ""I am almost collapsing under all my responsibilities."" A glimpse into the tragic end to the scientific flowering of pre-Nazi Germany along with Einstein's explanation for why it all happened A rare letter from a brief but consequential period in Einstein's life: after he left Germany but before he arrived in America Einstein had long been a revered scientist and member of the Prussian Academy of Sciences and was employed by Berlin University. At the beginning of March 1932 he returned to Germany from a visit to the United States where he had discussed heading the soon-to-open Institute for Advanced Study in Princeton New Jersey. He determined to accept and to spend half the year in Berlin and half the year in Princeton. But that year the Nazis were on the rise. It was becoming increasingly obvious to Einstein that his life was in danger. A Nazi organization published a magazine with Einstein’s picture and the caption “Not Yet Hanged” on the cover. There was even a price on his head. In December 1932 Einstein again left Germany to be a visiting professor at CalTech in Pasadena California. When Hitler was appointed German chancellor on January 30 1933 the physicist had just arrived in New York on his way to California to lecture on his theory of relativity. Nazi persecution of Jews in Germany was now open swift and often violent. Prominent Jews were denounced by Nazi officials attacked in the media and subjected to violence and arrest. As a vocal opponent of Nazism and a staunch advocate of pacifism Einstein was a particularly attractive target. Fortunately at the time Hitler came to power Einstein was already in the United States. Nonetheless the Nazis publicly agitated against Einstein as a symbol of “Jewish degeneracy” and accused him of spreading “atrocity propaganda.” In February and March 1933 the Gestapo repeatedly raided his family’s apartment in Berlin. Despite his own March 15 1933 declaration of self-imposed exile from Nazi Germany as well as warnings from friends that it was too dangerous to return Einstein and his wife decided to travel back to Germany intending to visit their summer cottage. At the end of March they arrived in Antwerp on the SS Belgenland owned by the shipping company Red Star Line. There they learned that Nazis had ransacked their cottage in Caputh at which point they decided that re-entering Germany was unwise. In April 1933 Einstein discovered that the new German government had passed laws barring Jews from holding any official positions including teaching at universities. Thousands of Jewish scientists were suddenly forced to give up their university positions and their names were removed from the rolls of institutions where they were employed. Einstein was now without a permanent home unsure where he would live and work and equally worried about the fate of countless other scientists still in Germany. He rented a house in De Haan Belgium where he lived for a few months. In late July 1933 he went to England for about six weeks where he was introduced to Winston Churchill. Einstein asked Churchill to help bring Jewish scientists out of Germany. British historian Martin Gilbert notes that Churchill responded immediately and sent his friend physicist Frederick Lindemann to Germany to seek out Jewish scientists and place them in British universities. In October 1933 Einstein returned to the US and took up his position at the Institute for Advanced Study. He had already revoked his German citizenship in Brussels and handed in his notice at Berlin University. He would never return to Germany. Michele Angelo Besso was a Swiss/Italian engineer. A Sephardic Jew by birth he was a close friend of Einstein during his years at the Federal Polytechnic Institute in Zurich and then at the patent office in Bern where Einstein helped him to get a job. Einstein called Besso ""the best sounding board in Europe"" for scientific ideas. In Einstein's original paper on special relativity he ended the paper stating ""In conclusion let me note that my friend and colleague M. Besso steadfastly stood by me in my work on the problem here discussed and that I am indebted to him for many a valuable suggestion."" After his resignation in 1890 Otto von Bismarck was venerated as unified Germany’s founding father not only during the remaining twenty-eight years of the monarchy but also albeit less emphatically in the Weimar Republic in Nazi Germany and in the Federal Republic. Throughout Germany numerous Bismarck statues are testament to the admiration. Hamburg has three. His memorialisation even went beyond Germany; the capital of the US state of North Dakota for example is named after him. Einstein was evidently not a proponent of the erstwhile unifier of Germany. As Einstein wrote of Bismarck’s influence ""The characteristic feature of this mentality is that people place the importance of what Bertrand Russell so tellingly terms “naked power” far above all other factors which affect the relations between peoples. The Germans misled by Bismarck’s successes in particular underwent just such a transformation of their mentality—in consequence of which they were entirely ruined in less than a hundred years."" In this letter he encourages Besso to let him have his suggestions for saving Hermann Weyl from the regime – through substituting him for Einstein on a proposed trip to Spain would seem disastrously tactless. He sends his regards to Anna Besso with the rueful remark that the German example bodes ill for an intellectual utopia which she had proposed. Weyl would go on work with him at Princeton. These two men were among Einstein's closest friends and colleague - Jewish or closely tied to Jewish relatives. He is rushing to get them out. Typed letter signed in German Le Coq-sur-mer Belgium May 5th 1933 to Besso. ""Dear Michele! I was not affected personally but just about everybody else who is kind of close to me was. Bismarck’s dismal education policy is wreaking havoc again with the German people. ""I would love to follow your suggestion regarding Weyl if I saw any possibility at all especially since I am almost collapsing under all my responsibilities. Even the slightest attempt to replace me with someone else in Spain would without a doubt be perceived as extremely upsetting. Have you not thought of that ""Rushed greetings to you Albert."" He writes a postscript: ""Greetings to Anna from me and tell her she can judge herself based on the current German conditions what her concept of 'island of intellectuals' would look like."" In July 1933 upon Einstein’s request a committee of 51 American artists intellectuals and political leaders came together to form the International Relief Association. Among them were the philosopher John Dewey the writer John Dos Passos and the theologian Reinhold Niebuhr. Other prominent citizens including First Lady Eleanor Roosevelt soon joined the effort. Its mission as The New York Times reported on July 24 1933 was to “assist Germans suffering from the policies of the Hitler regime.” But Einstein did much more. He tried to persuade political leaders in the United States and Europe to take action to help the Jewish populations at risk particularly those of his colleagues in Germany's scientific community which was very hard hit. He worked tirelessly to help Jewish refugees escape the Nazis and to find them places of refuge and employment. Many immigrants to the United States during the mid to late 1930s were Jewish between 1939 and 1940 more than half of all immigrants were Jews most of them refugees fleeing persecution in Europe. <img class=""alignnone wp-image-22732 size-post-window"" src=""https://cdn.raabcollection.com/wp-content/uploads/20231204162353/Folder-site-1600x1327.jpg"" alt="""" width=""1600"" height=""1327"" /> unknown
