Gustav Karl Wilhelm Hermann Karsten

Born in Stralsund, he followed the example of Alexander von Humboldt and traveled 1844-56 the northern part of South America (Venezuela, Ecuador and Colombia). From 1856 to 1868, he was a professor at the agricultural college in Berlin, afterwards serving as a professor of plant physiology at the University of Vienna (1868–72).[1] In 1881, at the suggestion of David Friedrich Weinland, Karsten became convinced of the correctness of Otto Hahn's organic theory of the chondrites and, as a result, wrote an essay entitled "Die Meteorite und ihre Organismen"[2] in which he declared his support for Hahn's theory. He died 1908 in Berlin-Grunewald.

As a taxonomist, he was the binomial author of many botanical species.[3]
