Picasso met Dora Maar in the winter of 1935. The poet Paul Éluard introduced Picasso to Maar while she was working as a photographer on Jean Renoir's film "Le Crime de Monsieur Lange". Although he was 26 years older than Maar, they were drawn together by a shared connection of art and politics. Maar pursued a career as a photographer and became involved in the Surrealist movement. She was Picasso's mistress until their breakup in 1945. It was Maar who documented Picasso's painting of "Guernica" by taking photographs of its development. Dora Maar was politically aware, articulate and persuasive, and may have had influence on Picasso's own political views. She was responsible for arranging the use of the studio on 7 rue des Grands Augustins, where Picasso created "Guernica" and also contributed to its development. Picasso first drew her portrait on 11 September 1936. She became his main model between the autumn of 1936 and spring of 1937. Picasso portrayed her as a tranquil figure until his creation of the weeping women paintings, which displayed a noticeable change in his approach to her.
