Heinrich Caro (February 13, 1834 in Posen, Prussia Germany now Poznań, Poland - October 11, 1910 in Dresden), was a German Chemist.He started his studiy chemistry at the Friedrich Wilhelms University and later chemistry and dyeing in Berlin at the "Royal Trades Institute". On the initiative of Nicolaus Druckenmüller, he trained as a calico printer in Germany, worked at Troost's calico printing works in Mülheim and then worked at the chemical firm Roberts, Dale in Manchester. During this time he improved the analysis of madder lake. After he returned to Germany he conducted his military service in 1857 and 1858. He worked in the Laboratory of Jaques Meyer the father of Victor Meyer in Berlin. In 1858 he was able to return to Mühlheim where he was not able to conduct his work. He joined the chemical firm Roberts, Dale in Manchester which he knew from his former visit.During his time in England he improved the extraction of Mauveins from the residues of the synthesis and developed a synthesis metode for aniline red and other dyes.In 1861 Caro returned to Germany and stayed at the laboratory of Robert Bunsen until he joined the Chemische Fabrik Dyckerhoff Clemm & Co. This chemical company later became The Badische Anilin und Soda Fabrik (BASF).Caro was responsible for indigo research at BASF and he and Adolf von Baeyer synthesised the first indigo dye in 1878.
