Jacob Beser (May 15, 1921 – June 16, 1992) was a lieutenant in the United States Army Air Forces who served during World War II. Beser was the radar specialist aboard the Enola Gay on August 6, 1945, when it dropped the "Little Boy" atomic bomb on Hiroshima. Three days later, Beser was aboard Bockscar when "Fat Man" was dropped on Nagasaki. He was the only person to have served as a strike crew member of both missions.
Jacob Beser grew up in Baltimore, Maryland where he attended the Baltimore City College high school graduating in 1938. Beser then studied mechanical engineering at Johns Hopkins University but dropped out the day after Pearl Harbor to enlist in the Army Air Forces. He was Jewish and extremely restless to get into the fight against Hitler. Because of his training and educational background Beser was sent to Los Alamos and worked on the Manhattan Project in the area of weapons firing and fusing. There he met or worked with various illuminaries in the Manhattan Project, such as Robert B. Brode, Norman Ramsey, Niels Bohr, Enrico Fermi, Edward Doll, and General Leslie Groves.
The unit that dropped the atomic bombs, 509th Composite Group, was activated at Wendover Army Air Field, Utah, December 17, 1944. The crews trained with practice bombs called “pumpkins” because of their size and shape, which was the same as “Fat Man” atomic bomb. The 509th deployed to Tinian in the Marianas in May 1945. It was a self-contained unit, with personnel strength of about 1,770 soldiers, mechanics, specialists and aviators. It consisted of the 393rd Bomber Squadron, the 320th Troop Carrier Squadron, the 390th Air Service Group, the 603rd Air Engineering Squadron, the 1027th Air Materiel Squadron, the 1395th Military Police Company, and the First Ordnance Squadron (in charge of handling the atomic bombs).
On August 6, 1945, the first atomic bomb to be used in warfare was dropped over the Japanese city of Hiroshima, instantly killing 80,000 civilians and military personnel and around 945 American prisoners-of-war and one British prisoner-of-war. The thirteen-hour mission to Hiroshima began at 0245 Tinian time. By the time the Enola Gay rendezvoused with its accompanying B-29s at 0607 over Iwo Jima, the group was three hours from the target area. Little Boy's detonation was triggered by radars on the bomb that measured its altitude as it fell. Beser's job was to monitor those radars and ensure that there was no interference that could have prematurely detonated it. The bomb fell away from the aircraft at 09:15:17 Tinian time. Beser did not visually watch the bomb detonate but he heard the bomb's radar signals switch on and then cut off at the moment the intense light generated by its detonation filled the plane.
In 1946, Beser was one of the founding members of Sandia National Laboratories, in New Mexico. He came home to Baltimore and in the mid-1950s began a long career working on defense projects for Westinghouse.
When asked about his atomic bomb missions on numerous interviews, Beser made the following response:
For years I have been asked two questions. (1) Would you do it again? (2) Do you feel any guilt for having been a part of Hiroshima's destruction?
One has to consider the context of the times in which decisions are made. Given the same set of circumstances as existed in 1945, I would not hesitate to take part in another similar mission.
No I feel no sorrow or remorse for whatever small role I played. That I should is crazy. I remember Pearl Harbor and all of the Japanese atrocities. I remember the shock to our nation that all of this brought. I don't want to hear any discussion of morality. War, by its very nature, is immoral. Are you any more dead from an atomic bomb than from a conventional bomb?
He died of natural causes in 1992 and was survived by his wife Sylvia, their four sons, and nine grandchildren. Before he died, he wrote his own book about the experiences of flying on both flights. The book is called "Hiroshima & Nagasaki Revisited" written in 1988.
