César Garcia was born in Madrid, and moved to France after the Spanish Civil War. He debuted as an illustrator in L'Essor in 1945. In 1947, his name appeared in L'Os Libre, Le Hérisson, Marius and La Presse. In addition, he worked in comics for a short period in his career. He drew 'Bidule et P'tit Sou dans la Planète Mars' in Goupil (1946) and two stories with 'Jim Okay' in O.K. (1947-48). He was also present in Francs-Jeux with 'Cézardette et Polochon' (1948-49) and 'Patinot et Ballinette' (1949-51), as well as 'Zip le Lutin Martien' (around 1958). These strips are often credited to Jean Cézard, who also worked for this magazine during this period. For L'Intrépide, he made the strip 'Gédéon' in 1949-50.
César eventually focused on illustrating current issues and caricatures, and began collaborations with magazines like Ridendo, Humour Magazine, Boléro and most notably Le Canard Enchaîné. For the latter magazine, he made a satirical strip of general De Gaulle as the elephant Babar in the strip 'Les Aventures de Malabar'. César's worked is characterized by the signature of a little lizzard at the bottom of his pages. He died of a cardiac arrest in 1964.
