Georges Paul Albert LEONNEC, born in Brest on September 30, 1881 and died in Kersaint on October 15, 1940, is a French illustrator, known in particular for his funny illustrations in "Le Sourire" or "La Vie parisienne". He is the son of cartoonist Paul LEONNEC and brother of writer-director Félix LEONNEC and Jannik LEONNEC, artist. From the age of 12-13, he began to work with his father on caricatures for Parisian newspapers. Expelled from the Lycée de Brest because of the caricature of a teacher, he continued his studies in Paris. Until he was 19, he hesitated between a "maritime" career and drawing. He is preparing for admission to naval school for two years on the vessel "Le Borda". Then Georges LEONNEC entered Decorative Arts. The year 1899 marks the beginning of the "Nantes years" for G. Léonnec. During this period he made many round trips between Brest and Nantes. He also often travels to Paris. In 1901 his first “professional” drawings were published in the review "Jean qui rit". His style is marked by Art Nouveau. In 1902 he published in "La Vie pour rire" and designed various works for periodicals such as "Le Rire", "Le Sourire" and "L'Assiette aueurre" as well as advertisements for the Byrrh firm, the Dufayel department stores and those "À l'Innovation" by Brussels. From 1900 to 1915 George LEONNEC led a life of "artist" which he shared with Élisa P. L’HOUEREUX, his first wife, from whom he was divorced in 1915. In 1907 he began to work for "La Vie parisienne", which was broadcast around the world. This is the birth of the light and naughty Parisiennes of George LEONNEC. From January 1908, a regular collaboration was established between the illustrator and the magazine. At the same time, he continued to produce advertisements published in "La Vie parisienne" for companies such as Renault and Daimler. These more or less undressed women were found on the covers of "Le Sourire" magazine during the 1920s. During the war he boosted the morale of the troops with his frivolous and humorous drawings which depict an archetype of naughty Parisian who appears on the cover of different popular magazines. In 1916, he met Hortense LE RETIF, whom he married in 1923. She became the model for "La Parisienne". And she gives him two daughters, Colette and Michèle. Colette served as a model for him in the 1930s. After the war, Georges LEONNEC signed for three covers of "La Vie parisienne" and "Le Sourire", and produced sets for the Folies Bergère and the Casino de Paris. He regularly corresponds with many artists of his time. Georges LEONNEC designed his last poster, for “Naja” cigarettes, in 1939, a creation that has remained unpublished. LEONNEC died in 1940 of cancer in Kersaint.
