Vidal was born in Constantine, French Algeria on 18 December 1908, to a middle-class family with origins in Castres, Mazamet, Carcassonne, and Gersoise.
In 1932, Vidal founded a consulting company, and served in the French military during World War II.
In the next election cycle, Vidal ran as an independent candidate, and was unseated by Antonin Tirefort.
Vidal also contested the 1968 legislative elections, which saw the defeat of Tirefort's successor, Jacques Limouzy.
Thereafter, Vidal retired from electoral politics, and ran the Center for Applied Psychology, which he had established.
