Viktor Zhdanov

Viktor Mykhailovych Zhdanov (Ukrainian: Віктор Михайлович Ждaнов; Russian: Виктор Михайлович Ждaнов, romanized: Viktor Mikhaylovich Zhdanov; 14 February [O.S. 1 February] 1914 – 14 July 1987) was a Soviet scientist, virologist and epidemiologist. He was instrumental in the effort to eradicate smallpox globally.

Zhdanov was born in the village of Shtepino, Russian Empire (in present-day renamed as Sviatohorivka, Donetsk Oblast, Ukraine). After Zhdanov graduated from Kharkiv Medical Institute in 1936, he spent the next decade working as an army doctor, where he became interested in epidemiology; this work would directly lead to his doctoral thesis on Hepatitis A. In 1946, Zhdanov was invited to become Chief of the Epidemiology Department of the I. I. Mechnikoff Institute of Epidemiology and Microbiology in Kharkiv, becoming its director two years later. His work in virus classification saw him admitted to the International Committee on Taxonomy of Viruses as a life member. In addition to his accomplishments in the field of public health, Zhdanov chaired the Soviet Union's Interagency Science and Technology Council on Molecular Biology and Genetics.
