Édouard Joseph Louis Marie Van Beneden (5 March 1846 in Leuven – 28 April 1910 in Liège) was a Belgian embryologist, cytologist and marine biologist.Dictionary of Biography Page 141 Houghton Mifflin Company - 2003 "Beneden, Edouard Joseph Louis-Marie van 1846–1910 * Belgian cytologist and embryologist Born in Liege," He was professor of zoology at the University of Liège. He contributed to cytogenetics by his works on the roundworm Ascaris. In this work he discovered how chromosomes organized meiosis (the production of gametes).

He is son of Pierre-Joseph Van Beneden, a zoologist and paleontologist.

Van Beneden elucidated, together with Walther Flemming and Eduard Strasburger, the essential facts of mitosis, where, in contrast to meiosis, there is a qualitative and quantitative equality of chromosome distribution to daughter cells.

Family Van Beneden's father, Pierre-Joseph van Beneden (18091894) was also a well-known biologist. He introduced two important terms into evolutionary biology and ecology: mutualism and commensalism.Boucher D.H. 1985. The idea of mutualism, past and future. In D.H.
