Joan Payson was born in New York City, the daughter of Payne Whitney and Helen Julia Hay. Her brother was John Hay Whitney. She inherited a trust fund from her grandfather, William C. Whitney and on her father’s death in 1927, she received a large part of the family fortune. She attended Miss Chapin’s School, then studied at Barnard College for a year, as well as taking some courses at Brown. She married lawyer and businessman Charles Shipman Payson, a native of Maine and a graduate of Yale University and Harvard Law School. Her husband was a Board member of Pepperdine University and together they provided the funds to build the university’s library that was named for them. In 1943, she established and endowed the Helen Hay Whitney Foundation (named in honor of her mother) for medical research. An avid art collector, she purchased a variety of artwork but favored Impressionist and Post-Impressionist works with her collection containing watercolors, drawings and paintings. She owned numerous pieces including those by James McNeill Whistler, Pierre-Auguste Renoir, Gustave Courbet, Maurice Prendergast, Jean Auguste Dominique Ingres, Honoré Daumier, Joshua Reynolds, Claude Monet, Henri Rousseau, Jan Provost, Édouard Manet, Lucas Cranach the Elder, Paul Cézanne, Henri Matisse, and Alfred Sisley. Payson was also a strong supporter of American artists, acquiring works by Thomas Eakins, Arthur B. Davies, Andrew Wyeth, Winslow Homer and John Singer Sargent. Payson donated significant works to the Metropolitan Museum of Art in New York City where the “Joan Whitney Payson Galleries” can be found.

The Joan Payson Collection is on permanent loan to the Portland Museum of Art in Portland, Maine and to Colby College in Waterville, Maine for one semester every two years. Regular educational tours of parts of the collection are offered to institutions throughout the United States. Joan Payson was a sports enthusiast who was a minority shareholder in the old New York Giants Major League Baseball club. She and her husband opposed moving the team to San Francisco in 1957. After the majority of the shareholders approved the move, Mrs. Payson sold her stock and began working to get a replacement team for New York City. Along with M. Donald Grant, the only other director who opposed the Giants’ move, Payson put together a group that won a New York franchise in the Continental League, a proposed third major league. The National League responded by awarding an expansion team to Payson’s group, which became the New York Mets. Payson served as the team’s president from 1968–1975. Active in the affairs of the baseball club, she was much admired by the team’s personnel and players. She was inducted posthumously into the New York Mets Hall of Fame in 1981. She was also the first woman to buy majority control of a team in a major North American sports league, rather than inheriting it. Joan Payson was instrumental in the return of Willie Mays to New York City baseball in May 1972 by way of trade and cash from the Giants.
