David Margolis (September 3, 1911 — October 8, 2003[1]) was an American artist known for his WPA murals in New York City.

At various times, the atrium was used as a storeroom, a cafeteria, office space, and a used-clothing repository for homeless patients.

In 1991, Bellevue underwent a major architectural redesign and the atrium was to become the main entranceway to the hospital (a significant upgrade from the two-door entrance crammed next to a concrete parking garage).

The Municipal Art Society helped track down Margolis, who had not seen the murals in half a century and never expected to see them again.

He touched up the murals that contained his parents, his childhood dog, a friend who had fought in the Spanish civil war, an influential art curator, and the nurses and doctors who had befriended him during the original painting sessions.

Margolis enjoyed evenings at the Savoy Ballroom with abstract expressionist Willem de Kooning,[3] and helped Diego Rivera install his murals at Rockefeller Center.
