Impressed by his work, the United States government tried to recruit him for an on-going centrifuge program but he was restricted from gaining the classified information on the United States' nuclear weapons program; he refused and returned to work with German firms.<ref name="slender"/> Following his return to Germany, the [[United States Atomic Energy Commission]] awarded contract works to its private firms to start work on the gas centrifuge, and marked his technical reports as classified documents on 1 August 1960.<ref name="slender"/>
