Since 1999, American Patrons of the Tate, a charity founded in 1987 to rally support in the Americas for London’s Tate Gallery, has raised over $100 million in cash and art donations. Now, in an effort to reflect its broad membership, it is changing its name to Tate Americas Foundation. The charity’s strongest contribution to the Tate is in acquisitions. Most people in the group have some connection to London, whether a home there, or through business or just through the art world, attending events like the Frieze art fair.
