Emil Knoevenagel

Heinrich Emil Albert Knoevenagel ( born June 18, 1865 in Linden near Hanover; † August 11, 1921 in Berlin, Heinrich Emil Albert Knoevenagel full name ) was a German chemist, researcher and journalist. He is one of the most important chemists of the early 1900's. According to him, the Knoevenagel reaction is named.

Family

After the New German Biography Emil was the son of a chemist and stenographers Dr. phil Knoevenagel Julius ( son of Theodor Patrimonialrichters from a family council in Mount Pearl ) and Friederike Jacobi ( the daughter of a car manufacturer from Linden ). Emil married in 1895 Elizabeth ( daughter of Ferdinand pharmacist Wocher and Gertrud Blankart ). The marriage went a son who fell in battle.

Life

After graduating from secondary school in Hanover in 1884 Knoevenagel studied at the Technical University in chemistry, among others in East and Hermann Wilhelm Friedrich Kohlrausch. In 1886 he moved to the University of Göttingen, where he studied with Victor Meyer in particular, where he received his doctorate in 1889. As this in Heidelberg successor of Robert Wilhelm Bunsen was Knoevenagel followed as an assistant and habilitated in 1892. Subsequently he became a Privatdozent. In 1896 he became an associate, 1900 Associate Professor of Chemistry in Heidelberg.

He worked among others with the synthesis of nitrogen heterocycles by condensation of 1,5- diketones with amines. The representation of unsaturated carbonyl compounds is named as Knoevenagel reaction (1896 ) after him.
