The Disney animator and inventor died at home of congestive heart failure, Forsse's wife Jan, 67, told NBC News, confirming the sad news that was first reported by the Teddy Ruxpin Facebook page.
"He had one of the most fertile creative minds I ever knew," she said. "He thought about Teddy all the time and was always writing stories."
Stories were Ruxpin's specialty. The talking toy bear had a cassette player in his back and his eyes moved as he "read" aloud. Introduced at Christmas in 1985, Ruxpin quickly sold out and was a best-selling toy the following year.
