Robert Desgabets

Robert Desgabets was a French Cartesian philosopher and Benedictine prior, born in Ancemont. He published two book-length philosophical works in his lifetime, Considérations sur l'état présent de la controverse touchant le T. S. Sacrement de l'autel in 1671 and Critique de la critique de la recherche de la verité in 1675.
In July 1658, Desgabets introduced the concept of blood transfusion or xenotransfusion at a meeting of Henri Louis Habert de Montmor's scientific society, which would later become the French Academy of Sciences. He would later publish Discours de la communication ou transfusion du sang in 1668.
