Fridolin Karl Leopold Spenner

from Wikipedia, the free encyclopedia

Fridolin Karl Leopold Spenner (born September 25, 1798 in Säckingen , † July 5, 1841 in Freiburg im Breisgau ) was a German botanist and university professor. Its official botanical author's abbreviation is “ Spenn. "

Live and act

The son of an administrative clerk in Upper Austria grew up in Tiengen and Villingen . Although Spenner showed a talent for drawing at an early age, his father insisted that he should study law.

He began his studies in 1815 at the University of Würzburg , where he took the subjects law and philosophy. After his father's death, he began studying medicine in Freiburg , along with natural history, especially botany. After his medical exam in 1821 he turned completely to the study of botany. During this time he particularly researched the flora around Freiburg. From 1825 to 1829 he brought out the three-volume “ Flora friburgensis ” as a result of his work , and for the first time in a German regional flora did not arrange the plant families according to the Linnaeus system , but according to a system that was then considered to be “natural”.

In addition to this work, Spenner published a description of the vegetation conditions in the Renchtal (1827) and the area around Freiburg (1838) as well as a floristic work on Nuphar minima im Feldsee (1827).

In 1826 Spenner moved to Schwetzingen to organize the herbarium of the local horticultural director Johann Michael Zeyher . In Zeyher's house he also met Karl Friedrich Schimper . In 1829 Spenner received his doctorate from the University of Freiburg with the dissertation “ Monographia generis Nigellae ” and shortly thereafter completed his habilitation with the work “Monographia generis Pulmonariae”, a work that was not published.

In 1832 he was appointed associate professor and in 1838 full professor at the medical faculty of the University of Freiburg, where he was given the "medical subjects of botany" and where he was director of the botanical garden alongside Perleb .
