Friedrich Schmitz (born March 8, 1850 in Saarbrücken , † January 24, 1895 in Greifswald ) was a German botanist . Its official botanical author's abbreviation is " F.Schmitz ".

Live and act

Schmitz studied mathematics and natural sciences at the University of Bonn from 1867 , especially with Johannes von Hanstein and Ernst Pfitzer . At Hanstein he became an assistant and published a work with him during his studies with the title " About the history of the development of the flowers of some Piperaceae ". In 1870 he studied at the University of Würzburg with Julius Sachs . In the same year he was drafted as a soldier for the Franco-German War . After his return he received his doctorate in Bonn with a thesis on the “ fibrovasal system in the piperaceae flower bulb ”.

Schmitz moved to the University of Halle , then to the University of Strasbourg , where he worked as a research assistant to Anton de Bary . In 1874 he qualified as a professor in Halle for botany and pharmacy.

In the following time he mainly devoted himself to the cryptogams , here especially the algae . He was able to prove that algae and fungal cells, which until then had been assumed to have no nuclei, not only contain one, but also other organelles, including the plastids . With his studies on freshwater and marine algae, he was able to show that the chloroplasts represent autonomous cell organelles and do not emerge " de novo ", but rather through division (Schmitz 1883). Schmitz also coined the term chromatophore .

In his investigations, Schmitz used for the first time in botany staining methods that zoologists had been using for a long time in their cell studies and that he had got to know during a study visit to the zoological station in Naples in 1878.

In 1878 he received an appointment as associate professor at the University of Bonn , where he worked for two years alongside Hanstein and was also custodian of the Botanical Garden from 1878 to 1884 . In 1884 he received a call to succeed Julius Münter at the University of Greifswald . In Greifswald he reorganized the botanical garden and set up special rooms for microscopic exercises.

In 1885 he was elected a member of the German Academy of Sciences Leopoldina .

Schmitz died of pneumonia .
