De Courcelles began his career driving cyclecars in Grands Prix, but was eventually hired by Lorraine-Dietrich to enter the inaugural 24 Hours. The two drivers ran together for the next two editions of the endurance event until they succeeded in 1925. The following year the two drove separate cars, with De Courcelles assigned to Marcel Mongin. Rossignol however, and new teammate Robert Bloch, went on to win the event once again, with De Courcelles and Mongin in second.
