CC GOQ OBE MSRC (November 26, 1904 – December 17, 1991) was a Canadian physician, microbiologist, and expert on tuberculosis from Quebec.

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 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.

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.
