From Wikipedia, the free encyclopedia :
Marie-Thérèse Walter (13 July 1909 – 20 October 1977) was the French mistress and model of Pablo Picasso from 1927 to about 1935, and the mother of his daughter, Maya Widmaier-Picasso. Their relationship began when she was seventeen years old; he was 45 and still living with his first wife, Olga Khokhlova. It ended when Picasso moved on to his next mistress, artist Dora Maar.
In Picasso's paintings, Walter appears as blonde, sunny, and bright, as in Le Rêve (1932), in contrast to his darker portrayal of Dora Maar, whom Picasso painted as the tortured "weeping woman".
