Heinrich Wilhelm Ferdinand Wackenroder (born March 8, 1798 in Burgdorf , † September 4, 1854 in Jena ) was a German chemist and pharmacist.

Life

After an apprenticeship as a pharmacist from 1814 to 1819, Wackenroder worked in his father's pharmacy. 1821–1824 and 1825–1826 he studied in Göttingen; for financial reasons he had to interrupt his studies for a year. He completed his dissertation in Göttingen with the chemist Friedrich Stromeyer and received his doctorate in Erlangen in 1827.

Since 1828 he was a professor at the University of Jena and an employee of Johann Wolfgang Döbereiner . They were both regular conversation and letter partners of Johann Wolfgang von Goethe , who was responsible for the chemistry institute he founded and in this function - in consultation with Duke Karl August - also awarded research contracts.

Services

In 1826, Wackenroder isolated the berberine- related plant alkaloid corydalin from the hollow lark's spur (Latin: Corydalis cava ) . Wackenroder was also isolating carotene from carrots during his doctoral thesis . Since the description of his results was not generally published until 1831 after he had become a professor in Jena, 1831 is usually considered to be the year carotene was discovered. Based on the detailed investigations of aqueous solutions of polythionic acids published by Wackenroder in 1846, such solutions are called Wackenroder's liquid . To explain his results, Wackenroder suggested "a new acid of sulfur", pentathionic acid .

From 1838 to 1854 Wackenroder was co-editor of the journal Archiv der Pharmazie of the Pharmacists' Association in Northern Germany. He was also the inspector of pharmacies in the Grand Duchy of Saxony .

Honors

In 1843 he was elected a member of the German Academy of Sciences Leopoldina .
