Agnes Rosenstiehl is the beloved writer and artist of nearly a hundred children's books, many featuring the deceptively simple antics of Mimi Cracra, Silly Lilly's French alter ego. In 1995, she received the prestigious Grand Prize for Children's Books from the Societe des Gens de Lettres. Agnes formally studied literature as well as music, and is married to an eminent mathematician. She lives in a country house with a garden, hidden in the center of Paris. She has four children and fifteen grandchildren.
