A pioneer of two-stage thermonuclear design
A 1955 memo from Zeldovich to Khariton stated: “The atomic implosion idea is due to Viktor Aleksandrovich Davidenko.”
Viktor Davidenko was a Soviet theoretical physicist and experimental researcher who helped shape the nuclear and thermonuclear weapons programme. He worked on neutron initiators and participated in the first Soviet atomic and hydrogen-bomb tests, while his late-1953 proposal to use an atomic explosion to compress a thermonuclear stage supplied the first conceptual step toward a two-stage design. The contribution fed into the subsequent work of Sakharov and Zeldovich and the Soviet thermonuclear system, but it was made within the secrecy and state direction of weapons science.

Related historical events
From factory worker to nuclear-weapons research leader
From 1930 to 1932 Davidenko worked as a lathe operator at a Leningrad factory while studying at an evening workers’ preparatory school. He entered the Leningrad Industrial Institute in 1932 and graduated with distinction in 1937. He then worked as a researcher at the Leningrad Physico-Technical Institute and as an engineer at factories under the People’s Commissariat of the Aviation Industry. In 1943 he was assigned to the USSR Academy of Sciences’ Laboratory No. 2, later the Kurchatov Institute, and entered nuclear research; from 1948 he worked at KB-11 in Sarov. There he advanced through research and departmental posts to head a section and become deputy scientific director; he headed a section in 1952. In 1963 he was transferred to the Kurchatov Institute of Atomic Energy and later worked at the Joint Institute for Nuclear Research. His career thus began in factory labor and technical education and led to positions of responsibility in state nuclear research institutions.
