Together with Gustave Saacké, Pierre Bailly planned numerous projects, including the Pavillon des Diamantaires for the architecture exhibition “1925, When Art Deco Beguiled the World” in Paris, the Stade Jean Bouin, as well as mansions and other projects in Venezuela. From 1917-20 Bailly was a student at the École des Beaux-Arts and then settled as an architect in Versailles. In 1928 he went to Venezuela with Saacké. Starting around 1930, he formed an architectural team with Saacké and Pierre Montenot for a short time. Together they won the gold medal in the Art Competitions at the 1932 Los Angeles Olympics in the category architecture, architectural designs, for their work Circus For Toros. It is odd that the jury gave the 1932 prizes to the three Parisian architects for their plan of a bullring, as it was difficult to connect bullfighting with the Olympic Movement. Bailly was also active as a painter and draftsman. In 1936, he was appointed a Knight of the Legion of Honor.
