Julius Tafel

Julius Tafel was a Swiss chemist and electrochemist.

Early life and education

Julius Tafel was born in the village of Choindez in Courrendlin, Switzerland on 2 June 1862. Tafel's father, Julius Tafel Sr. studied chemistry in Tubingen and became a director of Von Roll’s iron and steel works located in Choindez in 1856, and then took a top management position in steel works located in Gerlafingen in 1863.
Tafel attended the Realgymnasium in Stuttgart and Nuremberg, then studied chemistry from 1880 in Zurich, Munich, and Erlangen. In 1884, he earned his Ph.D. under Emil Fischer, who had joined Erlangen in 1882. Tafel followed Fischer to Würzburg in 1885 as his private assistant and completed his habilitation in 1888.

Work

He worked first with Emil Fischer on the field of organic chemistry, but changed to electrochemistry after his work with Wilhelm Ostwald. He is known for the discovery of an electrosynthetic rearrangement reaction of various alkylated ethyl acetoacetates to form hydrocarbons, now called the Tafel rearrangement, and the Tafel equation, which relates the rate of an electrochemical reaction to the overpotential. He is also credited for the discovery of the catalytic mechanism of hydrogen evolution. Tafel retired aged 48 due to ill health but continued to write book reviews until his death.

Death

Tafel suffered from insomnia and eventually had a complete nervous breakdown. He committed suicide in Munich in 1918.
