Daniel Louis Castellaneta was born on October 29, 1957, at Roseland Community Hospital on Chicago's south side and was raised in River Forest and Oak Park, Illinois.[1][2][3] He is of Italian descent, born to Elsie (née Lagorio; 1926–2008) and Louis Castellaneta (1915–2014),[4][5][6] an amateur actor who worked for a printing company.[7]

Castellaneta became adept at impressions at a young age and his mother enrolled him in an acting class when he was 16 years old. He would listen to his father's comedy records and do impressions of the artists.[7] He was a "devotee" of the works of many performers, including Alan Arkin and Barbara Harris and directors Mike Nichols and Elaine May.[2] He attended Oak Park and River Forest High School[8] and upon graduation, started attending Northern Illinois University (NIU) in the fall of 1975.[9]

Castellaneta studied art education, with the goal of becoming an art teacher.[7] He became a student teacher and would entertain his students with his impressions.[2][7] Castellaneta was a regular participant in The Ron Petke and His Dead Uncle Show, a radio show at NIU. The show helped Castellaneta hone his skills as a voiceover actor. He recalled "We did parodies and sketches, we would double up on, so you learned to switch between voices. I got my feet wet doing a voiceover. The show was just barely audible, but we didn't care. It was that we got a chance to do it and write our own material."[9] He took a playwriting class and auditioned for an improvisational show. A classmate first thought Castellaneta would "fall on his face with improvisation" but soon "was churning out material faster than [they] could make it work."[9]

Career
Early career
Castellaneta began his acting career after his graduation from Northern Illinois University in 1979.[7] He decided that if his career went nowhere he would still have a chance to try something else.[7] He began taking improvisation classes, where he met his future wife Deb Lacusta. He started to work at The Second City, an improvisational theatre in Chicago, in 1983 and continued to work there until 1987.[2] During this period, he did voiceover work with his wife for various radio stations.[7]

He auditioned for a role in The Tracey Ullman Show and his first meeting underwhelmed Tracey Ullman and the other producers. Ullman decided to fly to Chicago to watch Castellaneta perform. His performance that night was about a blind man who tries to become a comedian and Ullman later recalled that although there were flashier performances that night, Castellaneta made her cry. She was impressed and Castellaneta was hired.[2]

The Simpsons
Castellaneta is most famous for his roles on the longestrunning American animated television show The Simpsons, most notably as Homer Simpson. The Tracey Ullman Show included a series of animated shorts about a dysfunctional family. Voices were needed for the shorts, so the producers decided to ask Castellaneta and fellow cast member Julie Kavner to voice Homer and Marge Simpson respectively, rather than hire more actors.[7][10] Homer's voice began as a loose impression of Walter Matthau, but Castellaneta could not "get enough power behind that voice" and could not sustain his Matthau impression for the nine to tenhour long recording sessions.[11]
