Have you seen the April 1955
Popular Mechanics article "Anyone can be a frogman" by Richard Garnett, accessible at
https://books.google.co.uk/books?id=y9w ... J&pg=PA113? It describes his encounter with Broussard, who was then vice-president of the world's first post-war scuba diving club, the
Club Alpin Sous-Marin.
Henri Broussard's name also crops up now and again in
Free Diving by Dimitri Rebikoff (New York: E. P. Dutton & Company, 1956). Rebikoff was an expert in the field of underwater colour photography and an active member of the
Club Alpin Sous-Marin. If the article and the book are to be believed, Broussard sounds like a hard taskmaster who fixed everybody up after first meeting them with an underwater session, regardless of their wishes or subaquatic experience.
