Oct 31, 2023 · The endosymbiotic theory was first articulated by the Russian botanist Konstantin Mereschkowski in 1905. Mereschkowski was familiar with work by botanist Andreas Schimper, who had observed in 1883 that the division of chloroplasts in green plants closely resembled that of free-living cyanobacteria.

Konstantin Sergeevich Mereschkowski was a Russian biologist and botanist, active mainly around Kazan, whose research on lichens led him to propose the theory of symbiogenesis – that larger, more complex cells evolved from the symbiotic relationship between less complex ones.
May 4, 2018 · In 1905, the Russian botanist Konstantin Mereschkowski first proposed symbiogenesis, or endosymbiotic theory. This theory states that organelles, which distinguish eukaryotes from prokaryotes, emerged though a mutually beneficial relationship between individual prokaryotes.
Konstantin Mereschkowski (Merezhkowsky) was famous for pioneering the theory of symbiogenesis, particularly the idea that chloroplasts originated as Cyanophyceae. Forced to leave Russia twice, probably both times because of sexual scandals, he lived in several different countries throughout his life.
