Stephen Hillenburg graduated from Humboldt State University with a bachelor’s degree in Natural Resource Planning and Interpretation, with an emphasis on marine resources. Three years later, he enrolled at the California Institute of Arts in Valencia, graduating in 1992 with an MFA in Experimental Animation. The following year, Hillenburg landed a job as a writer and director on the Nickelodeon cartoon Rocko’s Modern Life before creating SpongeBob SquarePants, which debuted on Nick in May of 1999.

The cartoon series, set in the underwater city of Bikini Bottom, has produced more than 250 episodes, two big-screen movies, and a Broadway show in its nearly 20 years on the air. The SpongeBob character and his pals Patrick Star, Mr. Krabs, and the rest of the gang also became merchandising icons.

In a 2009 interview with Boston.com, Hillenburg commented on SpongeBob‘s 10-year milestone, admitting that he “never imagined working on the show to this date and this long.”

“It never was possible to conceive that… I really figured we might get a season and a cult following, and that might be it,” he said.

Stephen Hillenburg also revealed that the SpongeBob series was inspired by his love of the classic Laurel and Hardy short films, explaining, “You’ve got that kind of idiot-buddy situation — that was a huge influence. SpongeBob was inspired by that kind of character: the Innocent — a la Stan Laurel.”
