Parker also served as chair of the Joint Anti-Fascist Refugee Committee's fundraising arm, "Spanish Refugee Appeal". She organized Project Rescue Ship to transport Loyalist veterans to Mexico, headed Spanish Children's Relief, and lent her name to many other left-wing causes and organizations. Her former Round Table friends saw less and less of her, and her relationship with Robert Benchley became particularly strained (although they would reconcile). Parker met S. J. Perelman at a party in 1932 and, despite a rocky start (Perelman called it "a scarifying ordeal"), they remained friends for the next 35 years. They became neighbors when the Perelmans helped Parker and Campbell buy a run-down farm in Bucks County, Pennsylvania, near New Hope, a popular summer destination among many writers and artists from New York.
