1945Best.-Nr. 125771945. Jeppson Morris. Hand-annotated diagram of the "Little Boy" atomic bomb 1945 provides a direct technical interpretation of the weapon used in the bombing of Hiroshima by a participant who bridged both its development and deployment. As weapons officer aboard the Enola Gay and a scientist present at Los Alamos Laboratory Jeppson occupied a rare dual role linking the Manhattan Project's design phase with the operational execution of nuclear warfare. His annotations explain the internal structure and function of the uranium gun-type bomb offering a contemporaneous explanation of how critical mass was achieved and how the weapon was triggered. The document situates technical knowledge of nuclear fission within the lived experience of those responsible for its first use in warfare during World War II. Jeppson Morris. "Little Boy" atomic bomb diagram. United States 1945. One-page black-and-white printed diagram with extensive handwritten annotations and arrows in ink signed at lower margin "Morris Jeppson / Weapon Test Officer / Enola Gay Mission / HIROSHIMA 6 Aug. 1945." The annotations identify and explain key components including "target U235" "projectile 235" and the process by which the bomb "Becomes critical mass with projectile" along with labeled elements such as the "electric detonator" "gun barrel" and "one of 4 radar antennas." The markings function as a technical overlay to the printed schematic clarifying both structure and mechanism from the perspective of the officer responsible for in-flight arming and monitoring of the device. The atomic bombing of Hiroshima marked the first combat use of nuclear weapons and introduced a new phase of warfare defined by unprecedented destructive capacity and strategic implications. Jeppson's role in both the scientific and operational dimensions of the mission positions this document within the immediate transmission of specialized knowledge from laboratory to battlefield. His annotations provide insight into how participants understood and communicated the bomb's function contributing to the historical record of nuclear science military technology and the transformation of warfare at the end of World War II. Light handling wear; diagram remains clear with strong legible annotations and signature. Overall very good. unknown books

1957Best.-Nr. 56750Nagasaki Japan: Kawano Miwa June 1st Showa 32 1957. 8vo. 164 4 pp. Red cloth gilt lettering in Japanese on front cover & spine faint tidemark on upper front & back covers minor shelfwear still VG- copy inscribed by the author on ffep. to Mrs. Hildreth July 5 1959 w/ tipped-in typed note about the work. First edition of this exceedingly scarce personal memoir recounting the author’s experiences and survival of the dropping of the Atomic Bomb on Hiroshima in 1945 at the end of World War II. Kawano b. 1918 was originally a student at Doshisha University Theology Dept. and forced to leave school due to illness was inducted into the Japanese Army in Manchuria and after his discharge studied medicine at Nagasaki Medical University. While working as a medical student in Hiroshima at the time he received burns and severe radiation exposure from the blast. Subsequently he devoted himself to the medical treatment and relief of the injured in Hiroshima and Nagasaki and by 1958 was in the first class of neurosurgery residents at the Oregon School of Medicine now OHSU under Prof. George Austin. He later returned to Nagasaki in 1960 to found the Department of Neurosurgery in the Nagasaki University School of Medicine which had been entirely destroyed in 1945 by the Nagasaki Atomic Bomb drop. The campus had been located less than half a mile from the epicenter of the explosion with the entire facility reduced to ashes by the blast. Kawano devoted his considerable skills to studying the nuclear blast survivors including papers on Whiplash Injury and Headache 1967 study of Post-traumatic Chronic Headache 1965; 1968 changes in the capillaries in the Great Occipital Nerve as well as the increase of Cerebral Aneurysms 1963.

1945Best.-Nr. 125531945. Van Kirk Theodore J. handwritten autograph letter signed 6 August 1945 provides a first-person account by the navigator of the B-29 Enola Gay addressing the operational risks of deploying the first atomic bomb and the crew's reaction to the magnitude of its detonation over Hiroshima. As navigator on the aircraft that carried out the 6 August 1945 mission Van Kirk 1921-2014 bore responsibility for the precise calculations necessary to deliver an unprecedented weapon under combat conditions. This manuscript supports research into World War II strategic air warfare the operational uncertainties surrounding the Manhattan Project's first use in combat and the technological anxieties inherent in deploying a weapon whose destructive capacity exceeded prior experience. His reflections illuminate both mechanical vulnerability and the psychological shock experienced by participants at the dawn of nuclear warfare. Van Kirk Theodore J. 6 August 1945. Two pages. Approximately 8.5 x 11 inches. In this holograph letter written in question-and-answer format Van Kirk considers the potential for catastrophic malfunction: "Could something have gone wrong during the flight or when the bomb was launched Of course - all kinds of things. We all know what can go wrong with airplanes even during pastime flying. The bomb could 'hang up' in the bomb bay and not launch cleanly. Therefore it would not fall as predicted and if not could cause damage or destroy the plane." Reflecting on the detonation itself he acknowledges: "Were the crew members surprised at the extent of the explosion Yes. The explosion was much greater than the test in New Mexico and much bigger than any of us could realize." He signs "Theodore J Van Kirk / Navigator - Enola Gay / 6 Aug. 1945." The manuscript preserves his language emphasizing both the technical fragility of the mission and the unforeseen scale of the weapon's destructive force compared to the Trinity test. Although composed retrospectively and dated to the day of the mission the letter contributes to the documentary record of how participants later described the uncertainties surrounding the first atomic combat deployment. Van Kirk's acknowledgment that the explosion exceeded expectations underscores the limited empirical frame of reference available even to trained officers briefed on the weapon's development. His discussion of bomb bay malfunction and aircraft vulnerability highlights the intersection of conventional aviation risk and revolutionary weapons technology in August 1945. Minor edge wear and light handling creases; ink strong and fully legible; paper clean. Overall very good to near fine condition. A substantive self-authored reflection on mechanical peril and the unprecedented scale of the first atomic explosion in warfare. unknown

1945Best.-Nr. 125481945. Van Kirk Theodore J. handwritten autograph letter signed 6 August 1945 provides a first-person account by the navigator of the B-29 Enola Gay addressing fears of blast damage and radiation exposure during the Hiroshima atomic bombing mission. As navigator on the aircraft that delivered the first deployed atomic weapon in warfare Van Kirk 1921-2014 occupied a critical operational role requiring precise calculations of speed altitude and distance to ensure both mission success and crew survival. This manuscript directly supports research into World War II strategic bombing the operational realities of the Manhattan Project and contemporary military understanding of radiation hazards at the moment nuclear weapons entered combat. His reflections reveal not only technical planning but also the limited scientific certainty conveyed to flight crews regarding the bomb's destructive and radiological effects. Van Kirk Theodore J. 6 August 1945. Two pages. Approximately 8.5 x 11 inches. In this holograph letter written in question-and-answer format Van Kirk addresses the risks anticipated by the crew: "Did you have any fears about the effects the atomic bomb would have on the Enola Gay and the crew Yes. The fact that the bombs shock waves might destroy or damage the airplane was a major concern." He recalls being advised by a scientist that "we think the airplane will be OK if you're 9 miles away when the bomb explodes" and explains that "it was to get speed and altitude - and therefore distance - that we stripped down our airplanes. We were 12 miles away when the bomb exploded." Regarding radiation he writes: "We were not greatly concerned. We were told that the mushroom shaped cloud was deadly radiation and to stay clear of it. Otherwise no equipment to protect from radiation. No crew members were affected." He signs "Sincerely / Theodore J 'Dutch' Van Kirk / Navigator - Enola Gay / 6 Aug. 1945." The manuscript preserves his phrasing underscoring the mixture of scientific briefing operational adaptation and residual uncertainty that characterized the mission. Composed retrospectively and dated to the day of the bombing the letter reflects how participants later articulated their understanding of radiation at a time when its long-term biological effects were not yet fully grasped by the broader public or as Van Kirk's statement suggests by operational crews. His emphasis on distance calculations and aircraft modification illustrates the intersection of scientific theory and practical military execution in August 1945 when strategic air power entered the nuclear age. The acknowledgment that no protective equipment was provided and that crews relied primarily on avoidance of the mushroom cloud contributes to the evidentiary record of early nuclear risk assessment within the U.S. Army Air Forces. Minor edge wear and light handling creases; ink strong and fully legible; paper clean. Overall very good to near fine condition.

1945Best.-Nr. 125471945. Van Kirk Theodore J. handwritten autograph letter signed 6 August 1945 offers a first-person reflection by the navigator of the B-29 Enola Gay on the most perilous moments of the Hiroshima atomic bombing mission and the psychological atmosphere aboard the aircraft. Theodore "Dutch" Van Kirk 1921-2014 a central member of the three-man flight deck crew provides direct testimony concerning the uncertainty surrounding the bomb's force and the crew's fear that the detonation might destroy their own plane. The letter supports research in World War II military aviation the operational history of the Manhattan Project and the lived experience of nuclear warfare from the American aircrew perspective. By fore grounding danger doubt and immediate reaction Van Kirk's account contributes to the documentary record of how participants later interpreted the unprecedented destructive power they helped unleash. Van Kirk Theodore J. 6 August 1945. Two pages. Approximately 8.5 x 11 inches. In this holograph letter written in question-and-answer format Van Kirk records: "What do you think was the most dangerous moment during the mission Undoubtedly the seconds when and right after the bomb exploded. The question was 'will the bomb blow up or severely damage the airplane.' Thankfully we got far enough away so this did not happen." Addressing crew morale he continues: "Were your fellow crew members anxious about carrying out the mission There was some doubt in everyone's mind about the force of the bomb. Would it damage or even destroy the plane. I was all assuaged the moment the bomb exploded." He signs "Theodore J 'Dutch' Van Kirk / Navigator - Enola Gay / 6 Aug 1945." The manuscript preserves his phrasing and emphasis underscoring both technical calculation and personal apprehension at the moment nuclear warfare entered combat history. Although composed retrospectively and dated to the mission itself the letter reflects the sustained historical reckoning with the atomic bombings and the strategic doctrine that followed. Van Kirk's language centers not on political justification but on immediate survival revealing the acute awareness among crew members that the weapon's effects were not fully predictable even to those tasked with delivering it. Such testimony is especially significant given that only a small number of crew members had direct visual access to the detonation and experienced the shock wave firsthand. Light handling wear and minor edge creasing; ink bold and fully legible; paper clean. Overall very good to near fine condition. A substantive and self-authored statement documenting the perceived mortal risk faced by the Enola Gay crew at the threshold of the nuclear age. unknown

1945Best.-Nr. 143931945. Jeppson Morris R. Autograph letter recounting his role in the Hiroshima atomic bombing mission written by the weapons test officer aboard the B 29 Enola Gay the aircraft that delivered the first atomic weapon used in warfare on 6 August 1945. Morris Jeppson served as the electronic officer responsible for the bomb's fuzing system and for arming the uranium bomb known as "Little Boy" shortly before it was released over Hiroshima. His recollections provide firsthand testimony concerning the selection of the mission crew the operational procedures followed aboard the aircraft and the technical responsibilities associated with the deployment of the atomic weapon during the closing days of World War II. Jeppson Morris R. Autograph Letter Signed. Three pages written on yellow lined paper composed as responses to a series of questions concerning the Hiroshima mission. The manuscript appears to be a draft with numerous corrections and annotations with both the questions and answers written in Jeppson's hand. Addressing how he was selected to fly on the mission Jeppson recounts: "The day before the mission there were 6 of us who had participated in the development and testing of the electronic fuzing system for atomic weapons. George called our group of 6 together and said it was decided that whether Jeppson or Lt. Leon Smith would fly the first mission scheduled for 6 August. He said a coin toss will decide. He tossed I got the assignment." When asked about his role aboard the aircraft Jeppson describes assisting Captain William Parsons in preparing the weapon after takeoff and monitoring the bomb's electronic fuzing system during the flight. He explains that shortly before the bombing run he entered the bomb bay and "replaced an electrical component plug in the bomb with a red coded plug that armed the bomb so that it would self detonate when it reached an elevation above ground of about 1800 feet." The letter concludes with reflections on the mission's perceived outcome noting that the detonation confirmed the operational success of the weapon's design. The Hiroshima bombing represented the first combat use of nuclear weapons and marked a decisive technological and political turning point at the end of World War II. Personnel involved in the Manhattan Project and the 509th Composite Group later became central witnesses to the development and deployment of atomic weapons. Jeppson's manuscript responses offer detailed technical and personal recollections concerning the operational procedures aboard the Enola Gay including the late decision to arm the weapon in flight and the responsibilities assigned to the crew members who developed the bomb's electronic fuzing system. The document provides insight into the internal mechanics of the Hiroshima mission as remembered by the officer who physically armed the weapon shortly before its release. Signed "Morris R. Jeppson" in a different pen. Light handling wear; overall excellent condition. A detailed firsthand account of the technical preparation and execution of the first atomic bombing mission. unknown

1945Best.-Nr. 127381945. Van Kirk Theodore J. signed and inscribed photograph of the Hiroshima Atomic Dome created post-1945 represents a direct visual and textual reflection by the navigator of the B-29 Enola Gay on the devastation wrought by the first atomic bomb used in warfare. Theodore "Dutch" Van Kirk 1921-2014 responsible for navigation during the 6 August 1945 mission from Tinian here annotates an image of the ruined cityscape transforming a documentary photograph into a vehicle for personal recollection and justification. The item supports research into World War II memory culture strategic bombing doctrine and the ways in which atomic bomb participants publicly framed civilian casualties and the ethics of total war in subsequent decades. Van Kirk Theodore J. Inscribed photograph. 8 ½ x 11 inches. Black-and-white photograph depicting the Hiroshima Atomic Dome standing amid surrounding devastation the skeletal structure isolated against a flattened urban landscape. In ink Van Kirk writes: "I remember after the explosion the airplane was hit with a big jolt It was not flak but the shock wave effect of an atomic explosion. 60% of the city had been instantly destroyed. The number of killed and missing was 80000. Unfortunately in modern warfare you cannot separate civilian and military targets. - Theodore J. 'Dutch' Van Kirk Navigator - Enola Gay 6 August 1945." The inscription combines operational memory-the shock wave striking the aircraft-with statistical casualty figures and a broader statement about the nature of twentieth-century warfare. Signed within the text. Produced decades after the event and dated to the day of the mission the photograph reflects the enduring historical reckoning with Hiroshima's destruction and the moral arguments advanced by those who carried out the bombing. Van Kirk's juxtaposition of physical sensation in the aircraft with quantified urban devastation links technical execution to human consequence while his statement regarding the inseparability of civilian and military targets situates the image within debates over strategic bombing and nuclear ethics. Minor surface wear and light handling marks; image clear with strong tonal contrast; inscription bold and fully legible. Overall very good to near fine condition. A significant inscribed image uniting one of the most recognizable architectural remnants of Hiroshima with a candid reflection by a principal participant in the first atomic bombing mission. unknown
