Aperçu de la biologie marine à l'Université de Liège au cours de ces cent vingt dernières années

The marine biology in the Belgian university of Liège was founded by Edouard Van Beneden (1846-1910) and Léon Fredericq (1851-1935). Van Beneden was specialized in morphology and embryology, while Fredericq was a physiologist and a biochemist. Van Beneden and his pupils made important investigations on the development and the structure of the Tunicata, especially on the Ascidia. Van Beneden's successor was Désiré Damas and after the Second World War Marcel Dubuisson stimulated the revival of the marine biology in Liège. Fredericq studied among others the physiology of Invertebrata and discovered hemocyanin in the blood of Molluscs. Henri Fredericq, but especially Zenon Bacq and Marcel Florkin on comparative biochemistry made the Liège University into a centre of modern research
