Ivan Kondakov

Ivan Kondakov (1857–1931) was a chemist in the Russian Empire who, as professor of pharmacology of University of Tartu, studied polymerisation and invented synthetic rubber in 1901.

In 1886, Kondakov was appointed as a laboratory assistant at the Department of Chemistry at the University of Warsaw. In December 1894, he defended his master's thesis in chemistry "О синтезе под вливнем хлористого цинка в раядь жировых содухания" at St. Petersburg University.

In 1895, he was appointed professor of pharmacy at the University of Tartu and worked in Tartu until 1918.

In 1899, Kondakov discovered the catalytic polymerization of dimethylbutadiene into a synthetic rubber-like substance. His research laid the foundation for the production of synthetic rubber in Germany during the First World War.

From 1918 to 1921, Kondakov worked at the University of Prague.

Kondakov had a house in the professors' district in Elva, where he lived from 1911 to 1918 and 1921 to 1931.
