Maurice-Albert Chénechot, who signed with Chen and his initials Mac, was born in Issoudun. He initially pursued a career in music and worked as a violin teacher, before turning to political cartooning in 1936. He worked for L'Echo des Marchés du Centre until 1942, and subsequently drew for La France au Combat (1944), Ici-Paris (1945), La Presse (1946) and Marius (1947).
He also made two books with drawings from local life in the Issoudun area in 1937 and 1938. His silent comic strip 'Riri' appeared in La Nouvelle République between 1951 and 1953. Afterwards, he continued as an illustrator for France Dimanche, Boléro, Radar, Paris-Jour and Détective. He retired in 1984.
