Stephen McDannell Hillenburg is the creator of SpongeBob SquarePants (1999), Nickelodeon's highest-rated cartoons for children and a staple of American television. He was born on August 21, 1961 in Fort Sill, a United States Army post in Lawton, Oklahoma, to Nancy (Dufour) Hillenburg and Kelly Neugent Hillenburg Jr. Raised in Anaheim, California, he became fascinated with marine biology as a child and later developed an interest in art. He started his professional career in 1984 teaching marine biology at the Orange County Marine Institute. He wrote 'The Intertidal Zone', a comic book about tide-pool animals which he used to educate his students. In 1989, two years after leaving teaching, Hillenburg enrolled at the California Institute of the Arts to pursue a career in animation. He was later offered a job on the Nickelodeon animated television series Rocko's Modern Life (1993), after his success with short films The Green Beret (1992) and Wormholes (1992), which he created while studying animation. In 1994, Hillenburg began developing The Intertidal Zone characters and concepts for what would become SpongeBob SquarePants. The show premiered in 1999 and has aired since then. He also directed The SpongeBob SquarePants Movie (2004), which he originally intended to be the series finale. However, Nickelodeon wanted to produce more episodes, so Hillenburg resigned as the showrunner. He went back to making short films, with Hollywood Blvd, USA (2014). In 2015, The SpongeBob Movie: Sponge Out of Water (2015) was released; the sequel to the 2004 film, it marked Hillenburg's return to the franchise, after he co-wrote the story and acted as an executive producer on the project. Aside from two Emmy Awards and six Annie Awards for SpongeBob SquarePants, Hillenburg also received an accolade from Heal the Bay for his efforts on elevating marine life awareness, as well as the Television Animation Award from the National Cartoonists Society. Despite all this, he was involved in public controversies, including one that centered on speculation over the SpongeBob character's intended sexual orientation. Hillenburg was diagnosed in 2017 with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. He stated that he would continue to work on his show for as long as possible. He died at age 57 on November 26, 2018 in San Marino, California, a year and a half after his diagnosis.
