About this person
Arthur Harden was born on 12 October 1865 in Britain and built his career around a question brewers had asked for centuries: what happens inside a fermenting vat? His investigations into sugar fermentation and the enzymes driving it revealed mechanisms no one had seen before. In 1929 he shared the Nobel Prize in Chemistry with Hans Karl August Simon von Euler-Chelpin for that work. He helped launch the Biochemical Society and spent twenty-five years editing the Biochemical Journal, shaping the field as it formalized. He died on 17 June 1940.
