In the summer of 1951 a young art historian called John Richardson met one of the greatest painters of the modern era. Richardson was part of Picasso's circle in the South of France for the rest of the 1950s and then spent the rest of his life writing the definitive biography of the Spanish artist. John Richardson spoke to Laura Sheeter in 2011. He died in 2019.
