Sérgio Jaguaribe (born February 29, 1932). Known as Jaguar, he is a Brazilian cartoonist and comic artist, his birth city being Rio de Janeiro. He was originally an employee of “Banco do Brasil”. Jaguar began to draw professionally in 1952, when he offered the weekly magazine "Manchete" some caricatures loosely inspired by the work of Franco-Hungarian cartoonist André François. After working for "Manchete" and the cultural monthly "Senhor", he became famous in the 1960s for his works, among which his illustrations for Sergio Porto's collections of satirical chronicles entitled "Febeapá" (acronym for "The festival of stupidities that plagues our country"), the chronicles mainly dealt with the petty mockery of the Military Dictatorship in Brazil, as well as his anthology of cartoons "Átila, você é bárbaro" ("Attila, you are a barbarian!"). In 1969, together with his fellow cartoonists Millôr Fernandes, Ziraldo and other journalistic celebrities, he founded the innovative satirical newspaper “O Pasquim”.
