‘SpongeBob’ creator Hillenburg dies at 57

LOS ANGELES—Stephen Hillenburg, who used his dual loves of drawing and marine biology to spawn the absurd undersea world of "SpongeBob SquarePants," has died, Nickelodeon announced Tuesday.

Hillenburg died Monday of Lou Gehrig's disease, also known as ALS, the cable network said in a statement. He was 57.

He had announced he had the disease in March 2017. His death comes just weeks after the passing of another cartoon hero in Marvel creator Stan Lee.

Hillenburg conceived, wrote, produced and directed the animated series that began in 1999 and bloomed into hundreds of episodes, movies and a Broadway show.

The eternally, obliviously jolly SpongeBob and his yell-along theme song that opened "Who lives in a pineapple under the sea?!" quickly appealed to college kids and parents as much as it did kids.

"The essence of the show is that SpongeBob is an innocent in a world of jaded characters," Hillenburg told The Associated Press in 2001. "The rest is absurd packaging."

Its vast cast of oceanic creatures included SpongeBob's starfish sidekick Patrick, his tightwad boss Mr. Krabs, and his always-exasperated neighbor Squidward Tentacles.

Hillenburg's undersea world of Bikini Bottom was a realm like no other, real or fictional. SpongeBob can play his nose like a flute and could not possibly be happier to work his fast-seafood job of flipping Krabby Patties.

But he has his troubles, too. He constantly fails his boat-driving test, forcing his frightened blowfish teacher to inflate. In one episode he suffers a broken butt and is afraid to leave his pineapple home for days.

"I don't want to face my fears," SpongeBob, voiced by Tom Kenny, says in another episode. "I'm afraid of them!"

Kenny presented Hillenburg with a special honor at the Daytime Emmy Awards in April, and said in his speech that Hillenburg himself is the embodiment of his main character.

"SpongeBob's vocal cords might be mine," Kenny said. "But SpongeBob's playful spirit of gentle anarchy, his humor and the joy he takes in his vibrant, colorful, musicfilled world come directly, directly, 100 percent from my good buddy, Mr. Stephen Hillenburg."

Born at his father's army post in Lawton, Oklahoma, Hillenburg graduated from Humboldt State University in California in 1984 with a degree in natural resource planning with a marine emphasis, and went on to teach marine biology at the Orange County Marine Institute.

While there he drew a comic, "The Intertidal Zone," that he used as a teaching tool. It featured anthropomorphic ocean creatures that were precursors to the characters on "SpongeBob."

Hillenburg shifted to drawing and earned a master of fine arts degree in animation from the California Institute of the Arts in 1992.

He worked on the Nickelodeon show "Rocko's Modern Life," from 1993 to 1996 before he began to build SpongeBob's universe, which showed off his knowledge of marine life and willingness to throw all the details out the window.

"We know that fish don't walk," he told the AP in 2001. "And if you know much about sponges, you know that living sponges aren't square."

The show was an immediate hit that has lost no momentum in the nearly 20 years since its creation and helped define the culture of Nickelodeon.

"He was a beloved friend and long-time creative partner to everyone at Nickelodeon," the network's statement said. "His utterly original characters and the world of Bikini Bottom will long stand as a reminder of the value of optimism, friendship and the limitless power of imagination."

Its nearly 250 episodes have won four Emmy Awards and led to an endless line of merchandise to rival any other pop cultural phenomenon of the 2000s.

Hillenburg is survived by his wife of 20 years Karen Hillenburg, son Clay, mother Nancy Hillenburg, and a brother, Brian Kelly Hillenburg.
