Nuclear weapon
Yulii Borisovich Khariton (Russian: Юлий Борисович Харитон, 27 February 1904 – 19 December 1996) was a Russian physicist and a leading scientist in the Soviet Union's nuclear weapons program. Since the initiation of the atomic bomb project by Joseph Stalin in 1943, Khariton was the "chief Nuclear weapon designer" and remained associated with the Soviet program for nearly four decades. In honour of the centennial of his birthday in 2004, his image appeared on a Russian postal stamp by the Russian government.
