Tsvet also spelled Tsvett or Tswett
died June 26, 1919, Voronezh, Russian S.F.S.R.
Italian-born Russian botanist and chemist.
He is credited with the discovery (in 1903) and application of
chromatography. In 1910 he described how he extracted plant
pigments with ether and alcohol and percolated the solution through columns of calcium carbonate or powdered sugar; the different pigments appeared as separate coloured bands. Tsvet discovered several new
chlorophylls and coined the words
chromatography and
carotenoid. His work was not discovered by mainstream Western scientists for nearly 30 years.
