In 1945, René PLASSERAUD asked Pierre DEVANT, Rodolphe GUTMANN, and then Henri JACQUELIN to become his partners.
The firm took on the name of "R. PLASSERAUD P. DEVANT R. GUTMANN H. JACQUELIN".
After the war, there was a period of intense activity. At that time, the team of attorneys was reinforced by the arrival of Pierre BEHAGHEL and Jean LECCA, who became partners in 1971. Soon after, Ernest GUTMAN, Marc-Henri JACQUELIN, and Yves PLASSERAUD became partners in 1972, followed by Gustave KOCH and Jacques FORT in 1973.
