Wilhelm Körner at the age of 70

Wilhelm Körner , also known as Guglielmo Koerner (born April 20, 1839 in Kassel , † March 29, 1925 in Milan ) was a German chemist who had been naturalized to Italy .

Life

In his hometown of Kassel, Körner attended secondary school and from 1855 to 1859 the higher trade school . First he took courses for mechanical engineers and engineers. In his last year at the vocational school, he also worked in the chemical laboratory that Karl Georg Winkelblech was head of as the successor to Robert Wilhelm Bunsen . On the advice of Winkelblech, Körner devoted himself entirely to chemistry. In 1859 he moved to the University of Giessen , where he received his doctorate philosophiae under Heinrich Will a year later . Körner remained in Giessen as Will's assistant until 1864, after which he worked - interrupted in 1865 by a six-month stay with William Odling - in Friedrich Kekulé's laboratory in Ghent .

When Kekulé received a call to the University of Bonn in 1867 , Körner also left Ghent to go to Palermo and join Stanislao Cannizzaro there. He was engaged in the study of aromatic compounds . In addition, his interest in botany led him to study the ingredients of a number of vegetables. In 1870 he accepted the chair for organic chemistry at the "Scuola Superiore di Agricoltura" (German Agricultural University) in Milan. From 1875 he also held a teaching position at the Technical University of Milan which he held until 1922 when he retired at the age of 83 for health reasons. In 1880 he took on the Italian citizenship and was director of the Agricultural College from 1899 to 1914.

Körner's scientific focus was on contributions to Kekulé's benzene theory . He also published works on pyridine , aspartic acid and quinoxaline, as well as on alkaloids such as those obtained from the Angostura bark .

Honors

Körner was a member of numerous scientific societies, including the Berlin Academy of Sciences , the Accademia Nazionale delle Scienze (Italia) , the Accademia Nazionale dei Lincei and the Royal Society . He was an honorary member of the German Chemical Society and was awarded the Davy Medal of the Royal Society in 1900 .
