Kalle was the son of the textile merchant Jakob Alexander Kalle and studied chemistry from 1857 under Carl Remigius Fresenius in Wiesbaden and then in Berlin. In 1861 he received his doctorate at the University of Marburg and was then a chemist at the J. Collins company in Saint-Denis , which produced fuchsine . In 1863 he founded his own company in Biebrich (with his father as a limited partner) for the production of fuchsin and soon began producing other dyes. From 1877 he also produced azo dyes , such as the Biebrich scarlet fever developed by Rudolf Nietzki in his company in 1879 . He also tried synthetic indigo production in 1890 and opened a pharmaceutical division in 1885. His brother Fritz Kalle was also involved in running the company. In 1904 he converted the company into a stock corporation which formed an association with the Hoechst paintworks and the Cassella company . He passed the management of the company on to his son Wilhelm Ferdinand Kalle .
