Christian Luerssen

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). He has a number of plant species named after him, such as Koeleria luerssenii (grass species) and Cassia luerssenii (family Fabaceae).
