Sergei Nikolaievich Winogradsky ForMemRS (or Vinogradskyi; Ukrainian: Сергій Миколайович Виноградський, Russian: Серге́й Николаевич Виноградский; 1 September 1856 – 25 February 1953) was a Ukrainian-Russian 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. He reported that Beggiatoa oxidized hydrogen sulfide (H2S) as an energy source and formed intracellular sulfur droplets. 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). In this early stage of his life, Winogradsky was "strictly devoted to the orthodox faith", though he later became irreligious.
He 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.
