Jeffrey Allen "Jeff" Bergman (born July 10, 1960) is an American voice actor, comedian, and impressionist.
 Bergman is a cartoon impressionist who has provided the modern-day voices of various classic cartoon characters, most notably with "Looney Tunes" and Hanna-Barbera characters.
 Bergman was the first to replace Mel Blanc as the voice of Bugs Bunny and several other Warner Bros. cartoon characters following Blanc's death in 1989.
 Bergman alternated with Joe Alaskey and Greg Burson in providing most of Blanc's voices for various Warner Bros. productions.
Joseph Tapley "Joe" Dougherty (November 4, 1898 – April 19, 1978) was an American voice actor and actor who provided the original voice of the Warner Bros. animation character, Porky Pig, starting with the character's debut in "I Haven't Got a Hat" in 1935 until "Porky's Romance" in 1937.
 After that, Mel Blanc took over the role and voiced Porky for 52 years.
 Dougherty spoke with a natural stutter which became one of the character's trademarks; Dougherty's inability to control his stutter was a factor in the part being recast.
Show Biz Bugs is a 1957 Warner Bros. "Looney Tunes" animated short directed by Friz Freleng and featuring Mel Blanc as the voices of Bugs Bunny and Daffy Duck.
I Tawt I Taw a Puddy Tat is a 2011 3D computer-animated short film starring the characters Sylvester, Tweety and Granny.
 The short is an adaptation of the 1950 song of the same name, sung by Mel Blanc.
 It features the voice of June Foray as Granny, and Blanc's archive recordings taken from the song for Sylvester and Tweety.
 The short was released theatrically with "Happy Feet Two".
Bacall to Arms is a 1946 Warner Bros. cartoon in the Merrie Melodies series, directed by Bob Clampett, in his second-to-last cartoon at Warner Bros. ("The Big Snooze" would be the last).
 Neither Clampett (he was left uncredited because he had left the studio before the cartoon was released) nor voice characterizations are credited.
 Mel Blanc's voice is recognizable as a fat theater patron, a husband in a newsreel, and the wolf's vocal effects.
 Impressionist Dave Barry portrays the voice of Humphrey Bogart while June Foray voices Lauren Bacall.
 The title refers both to Hemingway's "A Farewell to Arms" and actress Lauren Bacall, whose acclaimed film debut was in "To Have and Have Not", based on another Hemingway novel, as well as a play on the term "A Call to Arms".
Gregory Lewis "Greg" Burson (June 29, 1949 – July 22, 2008) was an American voice actor and impressionist, who was best known for being a voice replacement for voice actors Daws Butler and Mel Blanc following their deaths in 1988 and 1989, respectively.
Bugs Bunny is an animated cartoon character; created in 1940 by Leon Schlesinger Productions (later Warner Bros.
 Cartoons) and voiced originally by Mel Blanc.
 Bugs is best known for his starring roles in the "Looney Tunes" and "Merrie Melodies" series of animated short films, produced by Warner Bros. During the golden age of American animation, his popularity increased.
 This era led to his becoming an American cultural icon and the official mascot of Warner Bros.
 Entertainment.
Noel Barton Blanc (born October 19, 1938) is a retired American voice actor, and son of late voice actor Mel Blanc.
Watson also provided the voice for Prince Chawmin' in the infamous Censored Eleven cartoon "Coal Black and de Sebben Dwarfs" (directed by Bob Clampett, 1943).
 However, he went uncredited in that cartoon because of primary voice artist Mel Blanc's contract agreement for solo credit.
 In a 1969 "Funnyworld" interview conducted by Michael Barrier and Milton Gray, Bob Clampett recalled Watson's name erroneously as "Zoot Watson"; thus, Leo Watson himself went uncredited for his work in the cartoon for almost forty more years.
 Finally, Australian voice artist and animation historian Keith Scott discovered his name correctly in the Warner Bros. Archives.
Haredevil Hare is a 1948 "Looney Tunes" cartoon directed by Chuck Jones.
 It stars Bugs Bunny and it is the debut for Marvin the Martian — although he is unnamed in this film — along with his Martian dog, K-9.
 All the voices are done by Mel Blanc.
 Marvin's nasal voice for this first film is different from the later one he is most known for, which was similar to one that Blanc used for the emcee in "What's Cookin' Doc?
", for just one line, where the emcee says, "Shall we give it to him, folks?"

Question: Who created the character that Mel Blanc was the voice for?
Answer: Leon Schlesinger Productions
