Ernest Borgnine (born Ermes Effron Borgnino; January 24, 1917 – July 8, 2012) was an American actor whose career spanned over six decades. He was noted for his gruff but calm voice and gap-toothed Cheshire Cat grin. A popular performer, he also appeared as a guest on numerous talk shows and as a panelist on several game shows.

Borgnine's film career began in 1951, and included supporting roles in China Corsair (1951), From Here to Eternity (1953), Vera Cruz (1954), Bad Day at Black Rock (1955) and The Wild Bunch (1969). He also played the unconventional lead in many films, winning the Academy Award for Best Actor for Marty (1955). He achieved continuing success in the sitcom McHale's Navy (1962–1966), in which he played the title character, and co-starred as Dominic Santini in the action series Airwolf (1984–1986), in addition to a wide variety of other roles.

Borgnine earned his third Primetime Emmy Award nomination at age 92 for his work on the 2009 series finale of ER. He was known as the original voice of Mermaid Man on SpongeBob SquarePants from 1999 until his death in 2012. He had earlier replaced the late Vic Tayback as the voice of the villainous Carface Caruthers in both All Dogs Go to Heaven 2 (1996) and All Dogs Go to Heaven: The Series (1996–1998).
