In 1927 Picasso met Marie-Thérèse Walter (1909-1977), a 17 year old who Picasso then lived with in a flat across the street from his marital home (while still married to Olga). Marie-Thérèse and Picasso had a daughter, Maya (Maria de la Concepcion) on October 5, 1935. (Picasso and Olga later separated although they remained married so Olga would not receive half of Picasso's wealth -- until she died in 1955. ) Picasso's relation with Marie was kept from Olga until Olga was told of Marie's pregnancy. Marie understandably became jealous when Picasso started to fall in love with Dora Maar in 1936, a year after Maya was born. It was Marie-Thérèse who was the inspiration for many of Picasso's famous Vollard Suite etchings. Marie-Thérèse died by hanging herself in 1977, four years after Picasso died. Maya's son, Olivier Widmaier wrote "Picasso: The Real Family Story" about his artist grandfather, in 2004.
