Grégoire Solotareff (born in Alexandria, Egypt in 1953) is a French artist, writer and illustrator of children's books. Solotareff practiced as a doctor from 1978 to 1985, before beginning his career as an illustrator with Hatier. The publication of his Loulou series from 1989 marked a turning point in his career, showcasing the bold lines and flat primary colours, inspired by Matisse and Van Gogh, that he would become known for. Loulou has sold over a million copies worldwide, but was only translated into English for the first time in 2017.
