Ernest De Nagy (Hungarian-American, 1881-1952) noted painter is known for his paintings of portraits, landscapes, still lifes, genre scenes, musicians, gardens, carriages, coastal and maritime scenes. He painted many famous portraits over the years including General "Blackjack" Pershing, whose portrait hangs at the Army Base in Arlington Virginia.

He usually worked in oil paint and painted in a realism style. He lived in Ogunquit, ME. Ernest's name and dates often get confused with his son's Ladislas (or Laszlo, or Lazlo) De Nagy (Hungarian, 1906-1944), who was also a noted painter and who passed away at an early age. He also had a daughter, Eva De Nagy (Hungarian-American, 1911-1999), who was a noted painter as well and who later owned the Eva De Nagy Art Gallery in Provincetown, MA.
