Wilhelm Giesbrecht

Wilhelm Giesbrecht (1854–1913) was a Prussian zoologist, specialising in copepods, during the "golden age of copepodology".
Giesbrecht was born in Gdańsk in 1854, and was educated in Kiel, where in 1881 he earned a Ph.D. in Baltic copepods under Professor Karl Möbius. He then moved to Naples to work at the zoological station there, staying there for the remainder of his life. His most famous work is the 1892 monograph Systematik und Faunistik der pelagischen Copepoden des Golfes von Neapel und der angrenzenden Meeres-Abschnitte ("Systematics and faunistics of the pelagic copepods of the Gulf of Naples and neighbouring seas"). In 1904, at the request of Anton Dohrn, Giesbrecht was made an honorary professor. He is commemorated in a number of species names:
Buntonia giesbrechti (G. W. Müller, 1894)
