French physicist, astronomer, mathematician and engineer
Gustave-Adolphe Hirn who made important measurements of the mechanical equivalent of heat and contributions to the early development of thermodynamics. He further applied his science in the practical development of steam engines. Hirn was born in Logelbach, near Colmar into the prosperous textile-manufacturing family Haussmann. Baron Haussmann was a cousin. At 19, he entered his grandfather's cotton factory as a chemist. Later he worked as an engineer, and began research on mechanics, especially on heat. He was received as a member of the French Academy of Science in 1867. In 1880, he founded a meteorological observatory near Colmar; and later devoted himself to astronomy. Hirn was educated in the shop, and his works are marked by much practical criticism of mere academic theory. Hirn invented the pandynanometer in 1880
