In January of 1927, outside the Galeries Lafayette department store in Paris, Picasso met Marie-Thérèse Walter, a striking 17-year-old, whose bourgeois family hailed from Maisons-Alfort in the city’s suburbs. The artist and notorious womaniser, who was then married to his first wife Olga Khokhlova, was instantly enchanted. “You have an interesting face,” he said to her. “I would like to do a portrait of you. I am Picasso.” Walter was not familiar with the name, but the artist was a man of great charm, and within a week the pair began a secret and ardent love affair that would last until 1941, with Walter going on to inspire some of Picasso’s most iconic artworks (three figures in Guernica were based on her) and bearing him his first daughter on September 5, 1935. The couple named her Maria de la Concepcion – Maya for short – after the artist’s beloved sister, Conchita, who died of diphtheria when he was 14.
