Utrillo was born in 1883 and his mother was Suzanne Valadon who became a model after a fall from a trapeze ended her chosen career as a circus acrobat.
She found that posing for Berthe Morisot, Pierre-Auguste Renoir, Henri de Toulouse-Lautrec, and others provided her with an opportunity to study their techniques; in some cases, she also became their mistress. Meanwhile, her mother was left to raise the young Maurice, who soon showed a troubling inclination toward truancy and alcoholism.
When a mental illness took hold of the 21-year-old Utrillo in 1904, his mother encouraged him to take up painting. He soon showed real artistic talent. With no training beyond what his mother taught him, he drew and painted what he saw in Montmartre.
