Harland_G._Wood--Joseph_Leo_Doob

Harland Goff Wood (September 2, 1907 – September 12, 1991) was an American biochemist notable for proving in 1935 that animals, humans and bacteria fixed carbon from carbon dioxide in the metabolic pathway to succinate.
(Previously CO2 fixation had been thought to occur only in plants and a few unusual autotrophic bacteria.)
