Painter and printmaker Jacques Soisson was born in February, 1928 in Paris, France. He began his artistic pursuit at the École des Beaux-Arts de Toulouse and continued at the École des Beaux-arts de Montpellier. There, he was professor of drawing from 1952 to 1962. Poisson's first exhibition took place in Paris in 1954, and he went on to show internationally, including in the United States, Canada, Belgium, Algeria, Switzerland, and more. The path of Art Brut and his interest in Surrealism, Abstraction and Expressionism led him to join the Société de Pscychopathologie de l’Expression, also attended by fellow Art Brut artist Jean Dubuffet. In 1966 he took up studies in child and adolescent psychotherapy, with the aim of creating a form of art therapy. He founded the "Atelier d'art-therapie" and collaborated with the Institut Édouard Claparède de Neuilly-sur-Seine, a child psychology clinic still in operation today. The works painted by his patients during this time were collected and donated to the Museum of St. Roch in Issoudun.

In 1969 Soisson joined the Société d’Art Brut, which was founded by Jean Dubuffet who was a friend of Soisson’s. Soisson decided to give up his career in child psychology and in 1978 dedicated himself to art. He continued to live and paint in Paris, France, until his death in 2012.
