From WWE:

WWE is saddened to learn that WWE Hall of Famer William James Myers, known to fans as George “The Animal” Steele, has passed away at the age of 79.

In 1985, however, Steele was embraced by the WWE Universe and changed the course of his career. After The Iron Sheik and Nikolai Volkoff abandoned him during a match, Steele fell back under the tutelage of the then-beloved Albano. His transformation was remarkable, as one of the most hated men in the sport became one of its most loveable figures. Long after his in-ring retirement and WWE Hall of Fame induction, George “The Animal” Steele’s name still evoked terror for one generation of WWE fans and warm smiles for another.
