Jerry Eisenberg passed away on February 11, 2025. Eisenberg was a celebrated animator, writer, producer, character designer, and storyboard artist on many classic Saturday morning cartoons. 

Eisenberg was a second generation cartoonist, his father Harvey Eisenberg was an animator on the original Tom and Jerry series and other MGM cartoons. Eisenberg left school in 1956 to join his father at MGM as an inbetweener on the Droopy cartoons. The studio shut down seven months after Eisenberg joined, but he moved on to Warner Bros. Cartoons and then later Hanna-Barbera Productions. 

At Hanna-Barbera, Eisenberg thrived as a creative. He co-created The Peter Potamus Show, and led character designed for Wacky Races and Super Friends. He also designed layouts for other classic Hanna-Barbera shows including The Jetsons, The Huckleberry Hound Show, Jonny Quest, and Wacky Races. According to his friend and cartoon writer, Mark Evanier, "There wasn't a single Hanna-Barbera production done between 1961 and 1977 that didn't have characters in it designed by Jerry."

After sixteen years at Hanna-Barbera, Eisenberg joined fellow Hanna-Barbera alumni Joe Ruby and Ken Spears at their new studio Ruby-Spears Productions. There he worked as a character designer and producer for Fangface, Plastic Man, and Thundarr the Barbarian. Other cartoons he worked on for other studios include Muppet Babies, House of Mouse, Dilbert, My Little Pony, Johnny Bravo, and Tom & Jerry Kids. He also worked on many of the direct to video Scooby-Doo movies. He is remembered by Evanier as "A truly great cartoonist and a helluva nice guy...one of the fastest artists I've ever seen and one of the nicest, jolliest guys."
