Life

Friedrich Oehlkers was born as a son of a minister in the being. After the Abitur it studied starting from 1910 at the University of Freiburg in mash gau biology. Influential teacher was the Botaniker Friedrich Oltmanns. 1914 it was drawn in as a soldier and hurt 1916 in the Argonnen heavily. A hand remained always During its convalescence leave it took its study with Karl knight of Goebel and locked it to 1917 with its thesis with the topic "“contribution for history and criticism of the Lamarckismus in the Botanik"”. 1918 state examinations in Botanik, Zoologie and chemistry at the University of Goettingen. Starting from 1918 Oehlkers was first trainee at Botani Institut of the University of Munich, starting from 1920 assistant at the fermentation-physiological laboratory in Weihenstephan and starting from finally 1922 assistant at Botani Institut of the University of with Ernst Lehmann.

In these years Oehlkers worked on differently topics such as Kernteilung of the Characeen, postflorale curvatures, Sporenbildung at Saccharomyceten, history of the development of Monophyllea. It already made 1921 under the influence of Otto racer, that worked at that time at botanischen Institut in Munich, leaving attempts at Oenothera, the plant type, which should employ it as research object the following decades.

In November 1922 Oehlkers at the University of habilitierte itself, where he worked until 1925 as a private lecturer. From 1928 to 1932 it worked as a full professor at the technical university Darmstadt. In April 1932 Oehlkers followed the call after the chair of the Botanik to the University of Freiburg in mash gau as a successor of its first academic teacher Friedrich Oltmanns. Since Oehlkers was woman of Jewish origin, he was suspended starting from 1933 constant chicaneries, in whose consequence he had to exercise its research work in a "“internal emigration"”. Despite all adversities its most important scientific realizations originate from this time: Starting from 1934 he worked on the physiology of the Meiosis and 1942/43 succeeded to him for the first time with his working group the proof that chemicals can release regularly mutations. In the USA its Institut was well-known in this time as "“Black Forest School OF Oehlkers"”.

After the total defeat of the Hitlerei Oehlkers was assigned to the university due to its political attitude during the "“third realm"” an important role with reconstruction. It was 1945 beside Constantin of the TZE, Gerhard knight, Adolf lamp and the theologian Franz Arthur Allgeier member in the "“clearing committee"” of the university. Despite the pursuit of its wife, whom it had been able to retain with trouble before the Deportation into an extermination camp and although his only son selected free death because of pursuit during the war, it occurred in this committee also for "“loaded"” university member, approximately for Martin Heidegger.

In this structure time Oehlkers held further offices at the University of Freiburg: Dekan of the scientific faculty, rector of the University of, initial member of the forerunner organization of the German research council DFG.

Outstanding vouchers for its didactical gift are among other things its text book "“the life of the plants"”, its contribution to the anniversary publication on the occasion of 70. Birthday of his friend Karl Jaspers 1953 or its commemorative address to the 500-Jahr-Feier of the University of Freiburg 1957.

Oehlkers emeritierte 1958, continued its research work at Streptocarpus and at Laubmoosen in the following years until 1967 at the genetic department of the botanischen institute.

Despite the heavy strokes of fate, which Oehlkers with its damage in the First World War or the pursuit of its family had to accept after 1933, despite most difficult conditions in building years after 1945, Oehlkers acquired itself a outstanding international reputation as Botaniker and Cytogenetiker and was model for some from it following the researcher generation, which its institutes in the time after 1960 with enrich material equipment and unimpaired from the course of the were allowed to develop.
