German botanist (1843-1916).
Christian Luerssen (6 May 1843, Bremen – 28 June 1916) was a German botanist. He was an authority in the field of pteridology. In 1872, at Leipzig, he graduated as a university teacher of botany, and was later appointed professor of botany at the Forest Academy at Neustadt-Eberswalde (1884). From 1888, he served as a professor at the University of Königsberg. After his death, a portion of his botanical collection (including European pteridophytes) was donated by Otto Bjurling to the Swedish Museum of Natural History. Luerssen was the taxonomic authority of the family Sciadopityaceae (1877).
