Sir Arthur Harden, FRS[1] (12 October 1865 – 17 June 1940) was a British biochemist.
His early education was at a private school in Victoria Park run by Dr Ernest Adam.
After receiving a Ph.D. he returned to Manchester as a lecturer and demonstrator and taught along with Sir Philip Hartog.
[4] At Manchester, Harden had studied the action of light on mixtures of carbon dioxide and chlorine, and when he entered the Institute he applied his methods to the investigation of biological phenomena such as the chemical action of bacteria and alcoholic fermentation.
He studied the breakdown products of glucose and the chemistry of the yeast cell, and produced a series of papers on the antiscorbutic and anti-neuritic vitamins.
