Between 1957 and 1963, Fromanger studied at the Académie de la Grande Chaumière and in night classes given by the City of Paris in Robert Lesbounit’s studio. He entered the Ecole nationale supérieure des Beaux-Arts, which he quickly left in order to work for two years in the studio of César. He met and became friends with Merri Jolivet, Gilles Aillaud, Eduardo Arroyo and Antonio Recalcati.
In 1964, Alberto Giacometti and Jacques Prévert introduced him to Aimé Maeght who asked him to join the gallery.
In 1965, Jacques Prévert wrote a preface to his work for the first time for an exhibition at the Galerie Maeght. Fromanger exhibited at the Salon de la Jeune Peinture a quintuple portrait of Gérard Philippe, Le Prince de Hombourg, an emblematic work in the transition from grey to color, marking the entrance of the artist into the New Figuration and Narrative Figuration movements.
In 1967, Fromanger left the Maeght Gallery and exhibited his Paysages découpés (Cut-up Landscapes) at Jean Taffany; in 1968, he exhibited at the Salon de Mai the first of his Souffle (Breath) sculptures and participated, in May and June, in the Atelier populaire de l’Ecole des Beaux-Arts, with the collaboration of the artists Aillaud, Arroyo, Buraglio, Jolivet, Le Parc etc. They would close it with the last poster, after the evacuation of the Beaux-Arts by the police at the end of the month of May: “La Police s’affiche aux Beaux-Arts, les Beaux-Arts affichent dans la rue” (“The Police Show Up at the Beaux-Arts, the Beaux-Arts Shows Up in the Streets”). Among the propositions by Gérard Fromanger that were rejected, that of using the tricolor flag, to make the red stain into the white and the blue; the poster would become a film with Jean-Luc Godard, then nine monumental spherical sculptures in Plexiglas, Les Souffles (The Breaths).
In 1970, Fromanger won the first prize of the Printmaking Biennial in Tokyo with the album Le Rouge.

In 1974, he participated in the 2nd trip undertaken by French intellectuals and artists to China and used it as an inspiration to create the series Le désir est partout (Desire is Everywhere), exhibited at the Jeanne Bucher Gallery in 1975.

In 1979, Fromanger executed the series Tout est allumé that the Jeanne Bucher Gallery refused to exhibit in 1980. That marked the ending of the collaboration between the artist and the gallery. Several months later, the series was presented at the Centre Pompidou by Pontus Hulten. It was the first solo exhibition of the artist at MNAM.
