Adolf von Baeyer (1835-1917), German chemist. Von Baeyer studied under Bunsen and Kekule, specialising in organic chemistry. He was the first to successfully deduce the structure of and synthesise the plant dye indigo. He also worked on the synthesis of the first barbiturate drugs, and proposed 'strain theory' to account for the stability of carbocyclic rings. He was awarded the Nobel Prize in Chemistry in 1905 'in recognition of his services in the advancement of organic chemistry and the chemical industry, through his work on organic dyes and hydroaromatic compounds'. This circa 1884-5 photograph is by Friedrich Mueller of Munich, Germany.
