Biography BAYER Adolf (Baeyer Adolf von)
(1835-1917)
Born October 31, 1835 in Berlin. At the end of the school enrolled in Berlin University. After a year's break from their studies associated with serving military service, decided to study chemistry, which was interested more in the school years. To do this, entered the University of Heidelberg, at the same time he worked in the laboratory of R. Bunsen, where he focused on the qualitative and quantitative analysis. In 1856 moved to A. Kekulц? von Stradonitz. Here is a short time synthesized a new organic substances - chlorides methylated arsenic (metilhloraminy). These studies formed the basis for his doctoral dissertation, which he defended in 1858. In 1860, Beyer returned to Berlin, where for 12 years occupied a place of organic chemistry teacher in a trade school, the future Higher Technical College. At the same time was a privat-docent, and then extraordinary professor at Berlin University. In 1872 headed the Department of Chemistry, University of Strasbourg, and three years later was invited to Munich, where he became the successor to Yu Liebig. He founded the New Chemical Institute, where under his leadership worked two generations of organic chemists.
Bayer works cover many sections of Organic Chemistry. Since his name is associated with the synthesis of indigo dye and study its structure (1878-1883), obtaining a new class of triphenylmethane dyes - phthalein, the synthesis of fluorescein, phenolphthalein, eosin. Bayer investigated reaction with water, in particular, opened the condensation of phthalic anhydride with phenols (1871) studied the pirrolovye and pyridine bases, compounds of uric acid, acetylene compounds. In 1885 he developed the theory of stress, explaining why the six-and five-membered carbon rings stable rings of greater or lesser number of carbon atoms. In 1887, while Armstrong suggested centric formula for benzene is close to the modern electronic formula.

Beyer died in Starnberg near Munich, August 20, 1917.
