KEILIN , DAVID

Keilin was born in Russia in Moscow and educated at Cambridge University. He was subsequently professor of biology at Cambridge from 1931 until 1952 and also director of the Cambridge Moltena Institute. His most important research was the discovery of the respiratory pigment cytochrome, which, he demonstrated, is present in animal, yeast, and higher plant cells. He also studied the biochemistry of the Diptera (true flies), and investigated the respiratory systems and adaptations of certain dipterous larvae and pupae.
