Maurice rose to being a top level pole vaulter in 1955. He was the national champion in 1962 and 1963. He took up coaching first with his 1964 Olympic compatriot Hervé d'Encausse who he coached to a bronze medal in the 1966 European Championships behind two future world record holders. Hervé's son Philippe d'Encausse is the coach of current world record holder Renaud Lavillenie. In the next two years Herve would hold the European record on two occasions. Other success stories included François Tracanelli who held the world junior record and would vault in two Olympics, Patrick Abada who also held the European record and Ferenc Salbert, winner of the 1989 Jeux de la Francophonie. In all his athletes would win 19 French national championships.
