Christian Andreas Victor Hensen (10 February 1835 – 5 April 1924) was a German zoologist (planktology). He coined the term plankton and laid the foundation for biological oceanography.
Hensen was born in the town of Schleswig. He studied medicine at the universities of Würzburg, Berlin (studying under Müller) and Kiel. In 1859, he received his doctorate in Kiel for a thesis on epilepsy and urinary secretions.
In 1867, he became a member of the Prussian House of Representatives to push towards studies of the ocean. Upon his initiative, the Royal Prussian Commission for the Exploration of the Oceans was founded.
From 1871 to 1891, Hensen was professor of physiology at Kiel. During his time, he was head of five marine biological expeditions to the Baltic and North Seas, as well as the Atlantic Ocean.
Hensen also worked in embryology and anatomy. He discovered a structure in the ear, the Hensen duct, also known as the Canal of Hensen. He also discovered Hensen's cells, Hensen's stripe), and two structures essential for the development of birds, the Hensen's node and Hensen's line.
The RV VICTOR HENSEN is a research vessel named in his honor.
