Jacques Doucet was born in Boulogne-Billancourt, France, on 9th April 1924. He was active as a painter. Doucet was interned as a political prisoner during the war, an experience which would have an effect on his work as a painter. He studied at the academy in Montparnasse at the end of the Second World War.
He met Corneille (1922-2010) in 1947, who involved him with the Dutch Experimental Group in Holland (1948). He drew the cover for the second issue of Reflex. He joined Cobra in 1948 together with Jean-Michel Atlan (1913-1960), within which he would be actively involved with maintaining contacts. His work was featured at both the exhibition in Amsterdam in 1949, as well as the one in Luik in 1951.
Doucet worked with all sorts of different materials. His work took on a much more abstract style after his contact with Cobra. His work was regularly on display at exhibitions in France, Belgium, Denmark and the Netherlands.
