Oscar Zariski — mathematician with roots in the Russian Empire
Oscar Zariski was a Belarusian-American mathematician born in Kobryn (Russian Empire, now Belarus) who became one of the towering figures of 20th-century mathematics. His work in algebraic geometry — particularly Zariski topology, which became foundational to modern algebraic geometry — transformed the field.

Born Oscher Zaritsky in Kobryn (Russian Empire) in 1899 to Bezalel Zaritsky and Hanna Tennenbaum, Zariski studied in Kyiv and Rome before settling in the United States. His Russian Empire Jewish origins and his European mathematical education combined to produce one of America's most original mathematical minds.
