Henry Richardson Procter (born May 6, 1848, in Lowlights at Tynemouth, † August 17, 1927, in Newlyn, Cornwall ) was a British chemist, who dealt with the chemistry of tanning processes in leather production. Procter's father ran a tannery and Procter first learned the trade from his father before studying chemistry at the Royal College of Chemistry in London. He then worked for tanneries and dealt scientifically with tanning. In 1891 he became a lecturer and later professor of leather chemistry at Yorkshire College (later the University of Leeds ). There he founded a research laboratory. In 1918 he became emeritus. He dealt with all areas of tanning and clarified the phenomenon of swelling of collagen in leather under the action of acid. He was a Fellow of the Royal Society. Less
