Armand Frappier, Canadian physician and microbiologist (d. 1991)
Armand Frappier (November 26, 1904 – December 17, 1991) was a physician, microbiologist, and expert on tuberculosis from Quebec, Canada.

Born in Salaberry-de-Valleyfield, Quebec, the son of Arthur-Alexis Frappier and Bernadette Codebecq, his mother died in 1923 from tuberculosis. This greatly affected him and he pursued a career devoted to fighting this tueuse de maman (mother killer). In 1924, he received a Bachelor of Arts and, in 1930, he received a medical degree from the Université de Montréal. In 1933, he obtained a Bachelor of Science also from the Université de Montréal.

In 1938, he founded the Institut de microbiologie et d'hygiène de Montréal - following the model of the Pasteur Institute in Paris and the Connaught Laboratories of the University of Toronto (Malissard, 1998; 1999a, 1999b, 2000)- the first French-language school of hygiene in the world, and served as its director for 38 years. It was renamed Institut Armand-Frappier in 1975.

He was instrumental in the fight against tuberculosis in Canada and as one of the first researchers to confirm the safety and usefulness of the Bacillus Calmette-Guérin vaccine.

In 1929, he married Thérèse Ostiguy. They had four children: Lise, Monique, Michèle, and Paul.
