In 1943 Picasso (age 62) then kept company with young art student Françoise Gilot (born in 1921).  Their two children were Claude (1947) and Paloma  (1949) who was named for the dove of peace that Picasso painted in support of the peace movement post World War II.  Gilot, frustrated with Picasso's relationships with other woman and his abusive nature left him in 1953.   Gilot's book "Life with Picasso" was published 11 years after their separation.  In 1970 she married American physician-researcher Jonas Salk (who later died in 1995).
