Melvin Jerome Blanc (born Blank ; May 30, 1908 – July 10, 1989) was an American voice actor and radio personality whose career spanned over 60 years. During the Golden Age of Radio, he provided character voices and vocal sound effects for comedy radio programs, including those of Jack Benny, Abbott and Costello, Burns and Allen, The Great Gildersleeve, Judy Canova and his own short-lived sitcom.

Blanc became known worldwide for his work in the golden age of American animation as the voices of Bugs Bunny, Daffy Duck, Tweety, Sylvester the Cat, Yosemite Sam, Wile E. Coyote and the Road Runner, Speedy Gonzales, Marvin the Martian, Foghorn Leghorn, the Tasmanian Devil, Pepé Le Pew and numerous other characters from the Looney Tunes and Merrie Melodies theatrical cartoons. Blanc also voiced the Looney Tunes characters Porky Pig and Elmer Fudd after replacing their original performers, Joe Dougherty and Arthur Q. Bryan, respectively, although he occasionally voiced Elmer during Bryan's lifetime as well. He later voiced characters for Hanna-Barbera's television cartoons, including: Barney Rubble and Dino on The Flintstones, Mr. Spacely on The Jetsons, Secret Squirrel on The Atom Ant/Secret Squirrel Show, the title character of Speed Buggy, and Captain Caveman on Captain Caveman and the Teen Angels and The Flintstone Kids. He was also the voice of Gideon's hiccups in Pinocchio, his only appearance at Disney. Blanc was also the voice of Woody Woodpecker in the first four animated shorts from 1940 to 1941, his only appearance at Universal Pictures. He also provided the screams for Tom and Jerry in the short films from 1963 to 1967, in just 34 short films directed by Chuck Jones.
