Hector J. Peabody, simply referred to as Mr. Peabody, is an anthropomorphic cartoon dog who appeared in the late 1950s and early 1960s television animated series The Adventures of Rocky and Bullwinkle and Friends, produced by Jay Ward. Peabody appeared in the "Peabody's Improbable History" segments created by Ted Key, and was voiced by Bill Scott. In 2014, he was featured in a computer-animated film, Mr. Peabody & Sherman. From 2015 to 2017, he appeared in a television series based on the film. Mr. Peabody's first name is never given or referred to in the cartoons, but in an animated promotion for the Rocky & Bullwinkle Savings Stamp Club he tells Sherman that it is "Hector".
