Feulgen, Robert

(1884–1955) German physiologist and chemist best known for his discovery of a selective staining technique for DNA, the Feulgen reaction, which is based upon the reaction of an aldehyde group with leucofuchsin. The intensity of the purple colour in the cell nucleus is used as a measure for the quantitative estimation of nuclear DNA.
