Mr. Peanut is the advertising logo and mascot of Planters, an American snack-food company and division of Kraft Foods. He is depicted as an anthropomorphic peanut in its shell dressed in the formal clothing of an old-fashioned gentleman: a top hat, monocle, white gloves, spats, and a cane.
Planters Peanut Company was founded in 1906, in Wilkes-Barre, Pennsylvania by Amedeo Obici and was incorporated two years later as the Planters Nut and Chocolate Company. In 1916 a young schoolboy Antonio Gentile, submitted drawings of an anthropomorphic peanut, a commercial artist, Andrew S. Wallach added the monocle, top hat and cane to create the iconic image. The schoolboy's family is believed to have received five dollars for the submission. 
There is a disputed claim that Frank P. Krize, Sr., a Wikes-Barre artist and head of the Suffolk plant, made the additions of the monocle, top hat and cane. Andrew Wallach's daughter, Virginia, maintains that Frank P. Krize joined the project after Mr. Peanut was created. Planter's history and other sources still in circulation, do not positively identify the artist. 
By the mid-1930s, the raffish figure had come to symbolize the entire peanut industry. Mr. Peanut has appeared on almost every Planters package and advertisement. He is now one of the best-known icons in advertising history.
While the character's television commercials were often accompanied by an elegant accented narrator, Mr. Peanut never had dialogue. On November 8, 2010, Planters announced that Mr. Peanut would officially be given a voice, supplied by American actor Robert Downey Jr.
Planters announced on July 1, 2013 that its mascot, Mr. Peanut, would be getting a new voice—that of comedian and Saturday Night Live alumnus Bill Hader, who is actually very allergic to peanuts.
- In the 2010 novel Mr. Peanut, a man fantasizes about killing his peanut-allergic wife by force-feeding her peanuts. "He poured out a handful and ate them and then wiped the salt from his empty hand on his pants. He looked at the chipper Planters Peanuts man tipping his top hat hello and thought about how one bite could kill Alice dead."
