Jean-Jacques Colin

Jean-Jacques Colin (16 December 1784 – 1865) was a French chemist known for his work in plant physiology, fermentation, and the chemistry of iodine. He collaborated with Henri-François Gaultier de Claubry on research demonstrating the interaction between iodine and starch, and with Pierre Jean Robiquet on the isolation of alizarin and purpurin from madder root. Colin held teaching positions at the École Polytechnique, the University of Sciences in Dijon, and the École spéciale militaire de Saint-Cyr. Over his career, he published research across chemistry, mineralogy, and biology, contributing to studies on seed germination, fermentation, dye production, and soap manufacturing.
