Henri Didon

Henri Didon (17 March 1840, in Le Touvet – 13 March 1900, in Toulouse) was a famous French Dominican preacher. He was also a writer, educator, and a promoter of youth sports. His outsize personality often put him in conflict with his religious hierarchy.

He coined the term ''Citius, Altius, Fortius'' for an 1891 youth sports competition he organized in Arcueil and that his friend Pierre de Coubertin was assisting. The latter proposed it as the official motto of the IOC in 1894. Provided by Wikipedia
