The French Zoologists, Casimir Cépède (1882-1954) and Rémy Perrier (1861-1936) both recieved France’s ultimate accolade, the Legion d’Honneur and were eminent, high achieving men in their day.
Casimir Cépède (left) however, is different. He studied Arctic plankton brought back by Jean-Baptiste Charcot after his historic French Antarctis Expedition and, to teach medical and scientific teams the characteristics of marsh insects, he created models of insects which could be assembled and disassembled.
Cépède also developed widely used tuberculosis and Spanish flu vaccines. Not content with that he founded Paris’s Institute of Applied Biology for the study of infectious diseases and their consequences. Alongside breakthoughs in Hematology and Pharmaceutical Botany studies, the Institute produced over 30 curative vaccines which were sold internationally.
Cépède was a lifelong, committed Socialist. He joined the french Socialist Party using the alias Élie Botte in 1905 & was friends with the biologist and radical, Alfred Giard. By 1947 he was on the Federal Executive Board of The Socialist Federation of the Seine. He was also an activist within the League for Human Rights, and the League for the Promotion of Cremation,
Juice on Perrier, who is best remembered scientifically for his studies of sea cucumbers, is non-existent.
In 1923, the seemingly unlikely collaborators, Cépède & Perrier began work on a series of wall charts for the students at the University of Comparative Anatomy and Zoology in Paris. Well loved and well used over time and in their browning, Sello-taped edged old age they add an unexpected bonus to the legacy of this odd couple of Zoology, Cépède & Perrier.
Whilst Cépède & Perrier would have sketched for and directed the making of these charts, neither man drew them. They were drawn by an unknown artist named “P. Méry” and edited by Jean Montaudon.

The table illustrates the aortic arches in the embryo (1, 2) and in the adults of Amniotic Vertebrates, in different groups of reptiles (3, 6), birds (7) and mammals (8).
The table illustrates numerous types of nerve cells. These include a complete motor neuron (1), interneurons (10), the cellular soma of different types of afferent neurons (14 ac), a cell of the glia (astrocyte) (9)..
