from Wikipedia, the free encyclopedia

Christian Heinrich Grasemann (born January 31, 1783 in Frankfurt am Main ; † October 28, 1838 there ) was a German doctor and botanist . Its official botanical author's abbreviation is “ Grasem. ".

Life

Grasemann was the son of the Frankfurt surgeon Johann Gottlieb Grasemann (* ~ 1742) and Wilhelmine Hottenrath (* 1753), born in Kassel in 1753. His two brothers Christian Friedrich and Johann Peter Grasemann were born in 1779 and 1788. He received his school education both from private teachers and from attending the Frankfurt grammar school. At a young age, he developed a fondness for natural history. He was particularly interested in botany, the early guidance of which he received from the Frankfurt city doctor and botanist Johann Scherbius . He gained his first anatomical knowledge through the care of Johann Jacob Behrends (1769–1823), who acted as a surgeon at the Anatomical Institute of the Senckenberg Foundation from 1798 to 1816 and taught young people interested in dissecting animal and human bodies.

In 1801 he began studying medicine in Jena with lessons in anatomy , physiology and surgery with Hofrat Justus Christian Loder , in chemistry and pharmacy with Johann Friedrich August Göttling , in natural history and botany with August Batsch and in mineralogy with Johann Georg Lenz (1748-1832) , the founder of the society for the entire mineralogy of Jena, of which Grasemann was appointed a member in 1802. In 1803 he continued his studies in Göttingen , where he was taught comparative anatomy by Johann Friedrich Blumenbach, among others . The following year he moved to Tübingen to Wilhelm Gottfried Ploucquet (1744-1814) where he received his doctorate in April 1807 with a dissertation on bone necrosis . In the same year he established himself as a doctor in Frankfurt am Main. From 1809 to 1815 he was employed as a collegiate and hospital doctor in the hospital of the Senckenberg Foundation . In addition, he was employed as director of the botanical garden and lecturer for botany and lived in the monastery. Until 1831 he was regularly listed as a practicing doctor in the annual state calendar of the Free City of Frankfurt.

Grasemann was the founder and actual member of the Wetterau Society for all natural history, founded in Hanau in 1808 . According to the board meeting on August 18, 1819, he was expelled from the society after eleven years of membership. With reference to the company's articles of association, the minutes read: “ Should Dr. Grasemann in Frankfurt, will be forgotten as a real member because of his faultless behavior ”. What Grasemann was guilty of has not been handed down. It is now believed that he did not follow the rule to make a material contribution within three years. In fact, however, he donated two unspecified dissertations and 64 dried, partly exotic plants to the Society in 1809 for its collection or library, as well as the volume Nomenclator entomologicus by Friedrich Weber, 1795, in 1814. Only his written essay is missing, but these have other well-known members never written either.
