Gerardus Johannes Mulder

Gerardus Johannes Mulder (December 27, 1802, Utrecht - April 18, 1880, Bennekom) earned a medical degree from Utrecht University. Mulder was a Dutch organic and analytical chemist who became a professor of chemistry at Rotterdam and later at Utrecht. While at the Utrecht University, Mulder described the chemical composition of protein. He claimed that albuminous substances are made up of a common radical, protein, and that protein had the same empirical formula except for some variation in amounts of sulfur and phosphorus. [This is long before the polymer nature of proteins was recognized after work by Staudinger and Carrothers.] He was the first to use this name, protein, coined by Jöns Jakob Berzelius in a publication, his 1839 paper 'On the composition of some animal substances'. In the same publication he also proposed that animals draw most of their protein from plants.

In 1850, he was elected a foreign member of the Royal Swedish Academy of Sciences.
