Black and white portrait of Cornelis A. Lobry de Bruyn (1857-1904). De Bruyn was an organic and pharmaceutical chemist and professor at the University of Amsterdam. His research on the three isomers of dinitrobenzene laid the foundation for the discovery of the Meisenheimer complex. In 1885, he discovered tautomerism in sugars, now known as the Lobry-de Bruyn-van Ekenstein transformation, and in the 1890’s he synthesized hydroxylamine (1891) and hydrazine (1894).
