Gustav-Adolf Hirn
Gustav-Adolf Hirn (born August 21, 1815 in Logelbach near Colmar in Alsace , † January 14, 1890 in Colmar) was a French physicist .
Life
In 1834, Hirn first joined a calico factory in Logelbach as a paint chemist and stayed in the same as an engineer after it had been converted into a cotton spinning and weaving mill in 1842. Here he began his fundamental research on the mechanical heat equivalent , with which he won a prize from the Berlin Physical Society.
He delivered numerous works on the theory of heat , the theory of the steam engine , fans and Amsler's planimeter , on frictional resistance , on the theory of overheating, the heat capacity of water; he also invented a panda dynamometer.
At the end of 1880 he founded a meteorological observatory near Colmar, where he continued his scientific work. In 1894 a memorial was erected for him there (see picture). In 1867 he became a corresponding member of the Académie des Sciences in Paris. From 1886 he was a corresponding member of the Russian Academy of Sciences in Saint Petersburg .
