Georg Matthias von Martens
He studied law at the University of Tübingen, where he also attended lectures by naturalist Carl Friedrich Kielmeyer and astronomer Johann Gottlieb Friedrich von Bohnenberger. From 1818 to 1821 he worked in Ulm, afterwards being based in Stuttgart, where in 1829 he became an official interpreter for Italian, Spanish and Portuguese at the Ministry of Justice and the Interior. From 1836 onward, he held the title of councilor.
As a botanist, he collected specimens from southern Germany, Austria and northern Italy. In 1832, with Gustav Schübler, he conducted botanical investigations in southeastern Württemberg. His European collections subsequently became part of the "Naturaliencabinet" in Stuttgart. He is also known for his studies of freshwater and marine algae, especially species native to eastern Asia. In 1862 he received an honorary degree in sciences from the University of Tübingen.
