Pablo Picasso & Olga Khokhlova // Olga was a Ukrainian-Russian dancer, a member of the Ballets Russes of Sergei Diaghilev, also known as the first wife of Pablo Picasso and the mother of his son, Paulo. Olga married Picasso on July 12, 1918 at the Russian Orthodox Cathedral in Paris. Jean Cocteau and Max Jacob were witnesses to the marriage. Khokhlova introduced Picasso to high society, formal dinner parties, and all the social niceties attendant on the life of the rich in 1920s Paris. Though her insistence on social propriety clashed with Picasso’s bohemian tendencies and the two lived in a state of constant conflict.
