Kohman worked on the Manhattan Project at the University of Chicago Metallurgical Laboratory and at Hanford, where he met his wife, Jane Sievers. He was an expert on radiochemistry and gamma ray sources. Kohman signed the Szilard Petition, and after the Manhattan Project, advocated for peaceful uses of nuclear energy.
