What was Stephen Hillenburg's Net Worth and Salary?

Stephen Hillenburg was an American director, animator, writer, producer, voice artist, and marine biologist who had a net worth of $120 million at the time of his death in 2018. That net worth number includes the value of his intellectual property rights, mainly his ownership of and future earnings from, SpongeBob SquarePants. In 2017, Stephen was officially diagnosed with ALS. A year later, he died at the age of 57.

After graduating from college, Stephen took various odd jobs before finding a teaching job at the Orange County Marine Institute. He spent the next three years teaching children about tide pool ecology, nautical history, diversity, and adaptation. Although the experience was rewarding, it helped Stephen realize that art was his true calling. As luck would have it, he had the opportunity to use his art skills to create "The Intertidal Zone," a picture book for young marine biology students. This illustrated book featured many characters that would later become the cast of SpongeBob SquarePants. Unfortunately, the book was rejected by publishers.

Stephen McDannell Hillenburg was born on August 21st, 1961, in Lawton, Oklahoma. Born on the US Army post of Fort Sill, Stephen spent just a year in Lawton before his family relocated to Orange County, California. His father left the army and started working as a draftsman and designer in the aerospace industry. Stephen was raised alongside a younger brother in Anaheim.

Hillenburg is, of course, remembered for creating the much-loved animated TV series "SpongeBob SquarePants." For the first three seasons, Stephen served as a showrunner with Nickelodeon. Today, the show has become the fifth-longest-running animated series in the United States. Before he ventured into the world of cartoons, Hillenburg was a professionally trained marine biologist. He once served as an instructor for the Orange County Marine Institute. During this period, he wrote a picture book about tide-pool animals. The experience led him to venture more toward a career in animation, and he subsequently studied animation at the California Institute of the Arts.

From a young age, Hillenburg became enamored by the films of iconic French oceanographer Jacques Cousteau. He also loved to explore tide pools and collect various animals. At the same time, Stephen also became interested in art and displayed considerable talents from a young age.

His first animation credits came with shows like "Rocko's Modern Life" with Nickelodeon. By the early 90s, he was developing many of his characters for "SpongeBob SquarePants," some of whom were based on his earlier picture book. The show first aired in 1999, and it is still running today. Along with acting as the showrunner and executive producer, Hillenburg is known for directing "The SpongeBob SquarePants Movie" in 2004 and for co-writing the script for "The SpongeBob Movie: Sponge Out of Water." In recognition of these achievements, Hillenburg has won two Emmy Awards and six Annie Awards.

As a high school student, Stephen played the trumpet and went snorkeling and diving in his spare time. This inspired him to study marine biology in the future. During this period, he also worked as a fry cook, which inspired SpongeBob's profession in the series. After graduating from high school, Hillenburg studied marine science at Humboldt State University. He also minored in art and developed his painting skills during his college years. Stephen eventually graduated in 1984 with a bachelor's degree in natural resource planning and interpretation, with a focus on marine resources.

In 1987, Hillenburg left his job to become an animator, enrolling in the Experimental Animation Program at the California Institute of the Arts. In 1992, he graduated with a Master of Fine Arts in experimental animation.
