Grisot was born in 1911 in Paris. At the suggestion of his family, he was trained as an engineer and even took a job as one in Besancon, France. However, Pierre Grisot secretly loved the arts and eventually enrolled himself at the Ecole des Arts Decoratifs in Paris. There he studied for one year before he began studies at the Ecole des Beaux Arts where he received a diploma as a drawing instructor. Grisot initially taught painting and drawing for a while but left after a short while to focus on his own art. Although he had been painting for some time, Pierre Grisot did not have his first official exhibition in Paris until 1942. After this, Pierre Grisot lived for a brief while in Tunisia and traveled the world exhibiting his work in Germany, Belgium, Sweden and the United States. He exhibited frequently in Paris, in particular at the Salon des Independants and with the group of ‘The Paris School’, showing together with the contemporary artists Vlaminck, Raoul Dufy and Villon.
