obituary

Heinrich Emil Albert Knoevenagel (born June 18, 1865 in Linden near Hanover , † August 11, 1921 in Berlin ) was a German chemist .

family

Emil was the son of the chemist and stenographer Julius Knoevenagel (the son of the patrimonial judge Theodor from a council family in Perleberg ) and Friederike Jacobi (the daughter of a car manufacturer from Linden). Emil married Elisabeth in 1895 (the daughter of the pharmacist Ferdinand Wocher and Gertrud Blankart). The marriage resulted in three children, son Walter died at the age of 17 as a war volunteer in northern France in 1915. Emil was also a staff officer on the Western Front from 1914 to 1918.

Life

After graduating from the Realgymnasium in Hanover in 1884, Knoevenagel studied chemistry at the Technical University there , with Hermann Ost , Wilhelm Kohlrausch and Karl Kraut , among others . During his studies he became a member of the Cimbria Hanover fraternity . In 1886 he moved to the University of Göttingen , where he studied in particular with Victor Meyer , from whom he received his doctorate in 1889 with contributions to the knowledge of the negative nature of organic radicals . When he succeeded Robert Wilhelm Bunsen in Heidelberg , Knoevenagel followed as an assistant and completed his habilitation there in 1892 on the subject of "asymmetric carbon". He then became a private lecturer . In 1896 he became an associate professor , and in 1900 a full professor of chemistry in Heidelberg.

Among other things, he dealt with the synthesis of nitrogen heterocycles by condensation of 1,5-diketones with amines. The preparation of unsaturated carbonyl compounds is named after him as the Knoevenagel reaction (1896).
