Philipp von Jolly

Johann Philipp Gustav von Jolly (26 September 1809 – 24 December 1884) was a German experimental physicist. He measured gravitational acceleration with precision weights and also worked on osmosis. He also designed several tools like the Jolly balance in 1864, a special eudiometer in 1878, as well as his own air pump and Jolly air thermometer.

Life Johann Phillip Gustav Jolly was born in Mannheim, He was knighted in 1854

One of Jolly's students at the Ludwig-Maximilians-Universität München was Max Planck, whom he advised in 1878 not to go into theoretical physics. Nevertheless, Planck's later work led to the discovery of quantum mechanics.

Philipp Carl obtained his doctorate in 1860 at the Ludwig-Maximilians-Universität München, supervised by von Jolly and Johann von Lamont.
