Günther Ohloff

Günther Ohloff (21 July 1924 in Tapiau near Königsberg – 9 November 2005 in Bernex near Geneva) was a prominent German fragrance chemist.

Ohloff was raised in East Prussia. When World War II erupted, he served in the German military, serving on the Eastern Front. He was severely wounded during the Battle of Stalingrad. After the war he studied Pharmacy at the University of Königsberg and Erlangen, as well as Chemistry at the Technische Hochschule Dresden. He received a Ph.D. in 1951, based on his work on the condensation of terpenes with formaldehyde (Prins reaction) unter the direction of Heinrich Wienhaus.

Ohloff began his career in 1951 with Schimmel & Co. () in Miltitz near Leipzig, at that time the most renowned flavor and fragrance company. In 1953 he left Eastern Germany to take a position with Dragoco, Holzminden. In 1959 he was offered a position at the Max Planck Institute for Bioinorganic Chemistry in Mülheim with Günther Otto Schenck. There he worked on the industrial-scale application of photooxygenation reactions employing singlet oxygen, ene reactions and sigmatropic rearrangements. Ohloff returned to Industry in 1962, joining Firmenich in Geneva to head the process-research group. He was named the firm's research director and member of the board of directors in 1968, which he remained until his retirement in 1989.
