Gustave-Adolphe Hirn (21 August 1815 – 14 January 1890) was a French
physicist,
astronomer, mathematician, and engineer 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.[2]
Life
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
calorics. Hirn carried out numerous experiments during his career, demonstrating the relevance of Carnot's principle in animated engines: the equivalence of thermal and mechanical energy. His work on thermodynamics is considered a major work of the 19th century. Indeed, he deduced from his work an equation of state that introduced both the notion of free volume and internal pressure,[3] notions that would reappear with the work of
van der Waals with a different corpuscular conception.
He was made a member of the
French Academy of Science in 1867; in 1880 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.[4]
He made significant contributions to the field of
tribology. His study of
friction in journal
bearings revealed all the essential features of fluid film
lubrication, although it lacked theoretical justification. For this contribution, he was named as one of the 23 "Men of Tribology" by
Duncan Dowson.[6]
