Gaston Ramon (September 30, 1886 - June 8, 1963) was a French veterinarian and biologist best known for his role in the treatment of diphtheria and tetanus.
He was born in Bellechaume (Yonne, France) and attended l'École vétérinaire d'Alfort from 1906 to 1910. In 1917 he married Marthe Momont, grandniece of Emile Roux.
During the 1920s, Ramon made major contributions to the development of effective vaccines for both diphtheria and tetanus. In particular, he developed a method for inactivating the diphtheria toxin and the tetanus toxin using formaldehyde which, in its essentials, is still used in vaccines manufactured today. He also developed a method for determining the potency of the vaccines, an essential element required for the reproducible production of these pharmaceuticals.
