Franz von Soxhlet

Franz Ritter von Soxhlet (January 12, 1848 Brno – May 5, 1926 Munich) was a German agricultural chemist from Brno. He invented the Soxhlet extractor in 1879 and in 1886 he proposed pasteurization be applied to milk and other beverages. Soxhlet is also known as the first scientist who fractionated the milk proteins in casein, albumin, globulin and lactoprotein. Furthermore, he described for the first time the sugar present in milk, lactose.

He was the son of a Belgian immigrant. He gained a PhD at Leipzig in 1872. In 1879 he became a professor of agricultural chemistry at the Technical University of Munich.[1]
