Maurice Sinet, who uses the pseudonym Siné, was born in Paris in 1928. After training as a typographer, he was so impressed by his first sight of the work of Steinberg that he immediately began drawing cartoons himself. He succeeded brilliantly not only in this field, but also as a book illustrator and designer of posters, stage decors, animated cartoons and publicity films.
Siné became especially famous for his cartoon cats. During the 1960s, he made several political cartoons for magazine L'Express, some of which were refused. He wrote a book about his life and work, titled 'Ma Vie, Mon Oeuvre, Mon Cul!' ('My Life, My Work, My Ass!').
