Prior to his marriage on 19 November 1953 to Donna Marella Caracciolo dei principi di Castagneto – a half-American, half-Neapolitan noblewoman who made a small but significant name as a fabric designer, and a bigger name as a tastemaker – Agnelli was a noted playboy whose mistresses included the socialite Pamela Harriman and even Jackie Kennedy. Though Agnelli continued to be involved with other women during his marriage, including the film star Anita Ekberg and the American fashion designer Jackie Rogers, the Agnellis remained married until his death of prostate cancer in 2003 at the age of 81. For most of his life, he was considered to be a man of exquisite taste. He left his extraordinary paintings to the city of Turin in 2002.
