Leon Smith Had Role in Assembling WWII Atom Bombs

Had a coin flipped the other way, Leon Smith would have been on the plane that dropped the atomic bomb ?Little Boy? on Hiroshima.
Smith, who grew up in Wisconsin, was pursuing an electrical engineering degree at the University of Wisconsin when he was drafted into the U.S. Army in 1943. When he suffered extensive hearing loss, he applied for a transfer to what was then called the Army Air Forces.
