Onésime Delafond


French veterinarian who was one of the primary representatives of veterinary science in France during the first half of the nineteenth century.

He served as a professor and director of the Maisons-Alfort veterinary school. He was a member of the Académie de Médecine and of the Société nationale d'agriculture.

Delafond is remembered for pioneer microscopic research of Bacillus anthracis, the causative organism of anthrax. Also, with microbiologist David Gruby (1810–1898), he performed extensive investigations of Tritrichomonas suis, a parasite found in swine.

In 1842 with Gabriel Andral (1797–1876) and Jules Gavarret (1809–1890), he was co-author of an important treatise on domestic animal blood composition. He co-published another treatise with Honoré Bourguignon.

He died on 15 November 1861, aged 56.
