Viktor Bunyakovsky

Viktor Yakovlevich Bunyakovsky (1804 to 1889) was a Russian mathematician and for 25 years vice president of the St. Petersburg Academy of Sciences. Born in Bar in Podolia governorate in the Russian Empire (now in Ukraine) he studied at the Sorbonne in Paris from 1820 and in 1825 completed his doctorate under the supervision of Augustin-Louis Cauchy. Back in St. Petersburg from 1826 he taught for much of his life, at the Naval Academy and at St. Petersburg University among other places, and published around 150 papers on theoretical mechanics and number theory and the Foundations of the mathematical theory of probability in 1846. He is credited with an early proof of the Cauchy-Schwarz inequality for the infinite dimensional case and for integrals in 1859 and the Bunyakovsky conjecture bears his name. The Academy established a prize in his name in 1875.
