Friedrich Thiergart

Friedrich Thiergart (born September 1, 1905 in Lübben (Spreewald) , † August 21, 1977 in Berlin ) was a German pharmacist , paleobotanist and paleynologist . He is considered one of the pioneers in pre-Ice Age pollen research.

Life

Friedrich Thiergart studied pharmacy at the Friedrich-Wilhelms-Universität zu Berlin , passed the pharmaceutical state examination in 1930 and then worked in the Nazareth pharmacy in Wedding .

In 1937 he was awarded a doctorate degree from the Friedrich-Wilhelms-Universität zu Berlin with a paleobotanical topic on pollen. phil. PhD .

After the end of the Second World War , the pharmacy founded in 1931 under the name Margareten-Apotheke in Berlin-Frohnau was burned out; the previous owner had poisoned himself with his wife before the Red Army marched in in April 1945. Friedrich Thiergart rebuilt the pharmacy at Ludolfingerplatz 2 in Frohnau together with his wife Berta (1906–1986), who was a licensed pharmacist and, as a Jew, was banned from working during the Nazi era. To help distinguish from the numerous Berlin Margaret Pharmacies he brought this in 1947 when the new foundation as Moose Pharmacy and forwarded it to pharmacy from that date until the year Furthermore, 1968. Of received Friedrich Thiergart shortly afterwards which was founded in 1948 Free University of Berlin one Teaching assignment for the introduction to pollen-analytical investigation methods in the field of palaeobotany .

In 1955 he became a member of the International Society for the History of Pharmacy .

His pioneering work as a paleobotanist is based on the fact that in 1949 he was the first researcher who attempted to record and represent the entire geological range of the spore content of the entire Mesozoic Era from the Keuper onwards.

Later he also examined the spores and pollen of the Oligocene fossil deposit in Rott and published his findings on the sporomorphic flora of Rott in the Siebengebirge in 1958.

His research trips, which he undertook with the director of the Berlin Botanical Garden and Museum Erich Werdermann , took him from Namibia to Spitzbergen .

In 1968 Friedrich Thiergart withdrew from business life and handed the pharmacy over to his former intern Albert Schatz, who had meanwhile successfully completed his apprenticeship as a pharmacist. Friedrich Thiergart was buried in August 1977 in the cemetery in Berlin-Hermsdorf, Frohnauer Strasse. After his wife Berta Thiergart, who died on September 7, 1986, was buried on the same grave site, the grave was then leveled after 20 years.

Friedrich Thiergart is the first to describe the taxon Aratrisporites saturni ( Thiergart 1949).

Karl Mädler named the genus Thiergartisporis Mädler , 1964 in his honor . Furthermore, the leading form Stellapollenites thiergartii ( Mädler , 1964), Clement-Westerhof et al., 1974, was named after Friedrich Thiergart , which is important for the chronostratigraphic structure of the triad .
