The Dia Art Foundation was established in 1974 in New York City by the not yet married Heiner Friedrich and Schlumberger heiress Philippa de Menil, as well as Helen Winkler.
They created the institution to help artists realize ambitious projects whose scale and scope is not feasible within the normal museum and gallery systems.
[5][6] With Friedrich and de Menil's combined large fortune, the foundation began supporting minimalist, conceptual, and land artists with, as Vanity Fair describes in an article, "stipends, studios, assistants, and archivists for the individual museums it planned to build for each of them".
[8][9] The foundation began by working with and collecting the work of only twelve artists: Joseph Beuys, Walter De Maria, Dan Flavin, Donald Judd, Imi Knoebel, Blinky Palermo, Fred Sandback, James Turrell, Cy Twombly, Andy Warhol, Robert Whitman, and La Monte Young.
[9] This gradual refocus is markedly seen in the 2018 acquisition of Sun Tunnels by Nancy Holt, Dia's most recent addition to their list of sites.
