Irwin Fridovich (August 2, 1929 – November 2, 2019) was an American biochemist who, together with his graduate student Joe M. McCord, discovered the enzymatic activity of copper,zinc superoxide dismutase (SOD),—to protect organisms from the toxic effects of superoxide free radicals formed as a byproduct of normal oxygen metabolism. Subsequently, Fridovichs research group also discovered the manganese-containing and the iron-containing SODs from E coli and the mitochondrial MnSOD (SOD2), now known to be an essential mammalian protein. He spent the rest of his career studying the biochemical mechanisms of SOD and of biological superoxide toxicity, using bacteria as model systems. Fridovich was also Professor Emeritus of Biochemistry at Duke University.
Lo! I have turned my face toward Him Who created the heavens and the earth, as one by nature upright, and I am not of the idolaters. [6:79]
