J. Michael Mendel, beloved producer of "Rick and Morty" and "The Simpsons," has died just two days before turning 55 years old. The cause of his death has not been made public. He is survived by his wife, casting director Juel Bestrop, and two children. From CNN:

Mendel worked on Fox's The Tracey Ullman Show, on which "The Simpsons" began its life as a recurring segment, before moving to the independent series.

He helped to create 207 episodes of "The Simpsons" over his time on the show, winning Emmys in 1995, 1997 and 1997. Mendel then produced 22 episodes of "Rick and Morty," winning a fourth Emmy for his work last year.

My friend, partner, and line producer Mike Mendel passed away. I am devastated. My heart breaks for his family. I dont know what Im going to do without you by my side Mike. Im destroyed.
