Starting with music, shifting on chemistry & finishing on botany, he pioneered CYCLE OF LIFE concept & researched extensively!!

Sergei Nikolaievich Winogradsky (1 September 1856 – 25 February 1953) was a Ukrainian microbiologist, ecologist and soil scientist who pioneered the cycle of life concept. Winogradsky discovered the first known form of lithotrophy during his research with Beggiatoa in 1887. This research provided the first example of lithotrophy, but not autotrophy. His research on nitrifying bacteria would report the first known form of chemoautotrophy, showing how a lithotroph fixes carbon dioxide (CO2) to make organic compounds.

Winogradsky was born in Kiev (then in the Russian Empire) and entered the Imperial Conservatoire of Music in St Petersburg in 1875 to study piano. However, after two years of music training, he entered the University of Saint Petersburg in 1877 to study chemistry under Nikolai Menshchutkin and botany under Andrei Sergeevich Famintzin. He received a diploma in 1881 and stayed at the St. Petersburg University for a degree of master of science in botany in 1884. Read more...
