Heinrich Debus
Heinrich Debus (born July 13, 1824 in Wolfhagen , Kurhessen , † December 9, 1915 in Kassel ) was a German chemist .
Life
His father was the dyer Valentine Debus. After his mother died in 1826 and his father married her sister, he grew up a little later with his grandparents.
In 1838 he attended the Kassel trade school, where Robert Wilhelm Bunsen taught him. He studied chemistry in Marburg from 1845 to 1848 , from 1847 as assistant to Bunsen. In 1848 he received his doctorate with a study on the red madder dye . (the first Marburg doctoral thesis in German). In 1851, when Bunsen went to Breslau, he received his habilitation.
At the suggestion of Friedrich August Genth , he followed this as professor in Marburg. In 1851 he also wanted to read chemistry history, but then followed a call to the Quaker institution in Hampshire, Queenwood College (possibly on the mediation of John Tyndall ), as successor to Edward Frankland . In 1856 he worked briefly at Liebig's laboratory in Munich. He also taught at Guy's Hospital and the Royal Naval College in Greenwich.
In 1861 he was elected a member of the Royal Society . After his return to Germany in 1888, he mainly devoted himself to historical work.
plant
He worked on gunpowder, organic sulfur chemistry, alcohol oxidation and hydrogen cyanide synthesis. In 1858 he first produced imidazole by reacting glyoxal with NH 3 , which is where the outdated name glyoxalin comes from. Hermann Kolbe denied that it was an aldehyde. In 1863 he synthesized methylamine by catalytic hydrogenation of hydrogen cyanide on platinum .
