In Martyl Langsdorf's Studio
Alexander Langsdorf Jr. was an American physicist on the team that developed the atomic bomb and several devices related to nuclear physics. During World War II, he worked with Enrico Fermi at the University of Chicago on the Manhattan Project. Langsdorf was one of the designers of the first two nuclear reactors after Fermi completed the first sustained nuclear chain reaction in 1942. Langsdorf was able to produce a tiny usable sample of plutonium using his device. That sample was then used in the Trinity nuclear test on July 16, 1945. Langsdorf urged President Harry S Truman not to use the bomb against the Japanese, but a plutonium-based bomb was dropped on Nagasaki soon after.
He continued to urge against expansion of nuclear weapons. He helped found Bulletin of the Atomic Scientists, and his wife Martyl Langsdorf designed the 1947 cover of the publication which debuted the Doomsday Clock.
