Born in 1881 in Paris, Picart Ledoux was a painter as well as an engraver, poet and writer. A student at the Beaux-Arts in Paris until 1902, he first lived in Montmartre and attended the Lapin Agile where he met Suzanne Valadon and her son Maurice Utrillo. There he also met Jules Romains, who wrote of him that he was powerful in his landscapes but also sensual in his nudes and deep in his portraits and that he was the last true impressionist, comparable to Renoir in research, until end of his life from the perfection of his art.
In 1910, the year of his first personal exhibition, he was received at the National Society of Fine Arts. In 1921, he became a friend of Aristide Maillol. From 1923, he exhibited all over the world. In 1934-1935, he produced a decorative ensemble for the liner Normandie and left Montmartre for Montparnasse. The national museums acquire many paintings and he obtains the great gold medal at the Universal Exhibition of 1937. On his death in Paris in 1959, his works appear in particular in the museums of Paris, New York, Moscow and Tokyo. His sons Yves and Jean (1902-1892) were respectively painter and tapestry maker.
