After studying western concert flute at the Conservatoire de Lille, Grimbert integrated the Conservatoire de Paris, where Olivier Messiaen and Darius Milhaud were his teachers among others.
On 1964 Grimbert conducted the "La Faluche" students choir, during the 5th Zimriya, a jewish international choir festival in Israel.
His multiple collaborations (Leonard Bernstein, Seiji Ozawa...) associated with his real desire to transmit to young artists gave rise to vocations, such as those of choral conductors Michel Laplénie, Laurence Equilbey, and Denis Rouger.
In February 2009, he was made a chevalier of the Légion d'honneur.
