Аннотация:Mikhail Semenovich Tsvet (also, Tswett, especially in botanical literature, 1872–1919, Fig. 1) was born in Italy, grew up in Switzerland, received his education at the University of Geneva, and moved to his father’s Russian homeland. His Swiss PhD degree was not recognized, and he had to augment his training; finally, earning a Master’s degree. He was a botanist who invented chromatography, which developed into one of the major tools of chemical and biochemical research in the twentieth century, alas, leaving Tsvet in relative obscurity. We remember him on the occasion of the 150th anniversary of his birth.
