Stephen Hillenburg has passed away at the age of 57 after a battle with ALS.
He's the creator of the international hit, "Spongebob Squarepants."
Hillenburg was diagnosed with ALS in March of last year. Nickelodeon tweeted sadness to hear of Hillenburg's passing, and today the network would be observing a moment of silence to honor his life and his work. Hillenburg leaves behind his wife Karen and their son Clay.
In the video above you'll see how his love of marine biology sent him down the path of creating the children's show adored by so many. RIP.
