Overview
Oscar the Grouch is a Muppet character created by Jim Henson and Jon Stone for the PBS/HBO children's television program Sesame Street. He has a green body, no visible nose, and lives in a trash can. Oscar's favorite thing is trash, as evidenced by the song "I Love Trash", with a running theme being his collection of seemingly useless items. Although the term "Grouch" aptly describes Oscar's misanthropic interaction with the other characters, it also refers to his species. The character was originally performed by Caroll Spinney from the show's first episode until Spinney's retirement in 2018. Eric Jacobson began understudying for the character in 2015, and officially took on the full role after Spinney's retirement in 2018.
Origins
Initially, the puppet characters on Sesame Street did not appear on the actual Sesame Street set, but were relegated to the intermediary segments. Muppets creator Jim Henson wanted them to be integrated into the series, suggesting a giant bird and also a creature living in the neighborhood's trash can. The character was developed by Sesame Street head writer Jon Stone and Henson. Puppeteer Caroll Spinney found inspiration for the voice in the driver of a New York City taxi he took to the studio. His first line was "Where to, Mac?".
Henson credits the character's name based on the personality of a "magnificently rude" restaurant owner and namesake of Oscar's Salt of the Sea which Henson and Stone frequented. Henson's office was on East 67th Street, just around the corner from Oscar's Salt of the Sea on Third Avenue. In the early 1960s, Henson and Stone often had lunch there and observed that the owner, Oscar Karp, dressed in black, looked unkempt, and had a gruff disposition.
