Arthur Morin

Arthur Jules Morin was a French physicist, born on 19 October 1795 and dying on 7 February 1880, who conducted experiments in mechanics and invented the Morin dynamometer. He introduced the term coefficient of friction and demonstrated its utility, which made his measurements of sliding resistance a reference point for later work on friction. In 1850 he was elected a foreign member of the Royal Swedish Academy of Sciences, and in 1859 he was conferred with Honorary Membership of the Institution of Engineers and Shipbuilders in Scotland. His name is one of the 72 names inscribed on the Eiffel Tower, and Duncan Dowson named him as one of the 23 Men of Tribology.
