The Jim Henson Company Facebook page announced the news on Saturday (Feb. 15). Henson died of a sudden heart attack at his home on Friday, Feb. 14. He is survived by four siblings — Lisa, Cheryl, Brian and Heather — along with a wife, Gyongyi, and daughters Katrina and Sydney.
Like almost everyone in the Henson family, John had a long history with the Muppets and other Jim Henson projects. He performed the over-sized character of Sweetums starting in the 1990s. John was also a shareholder and board member of the Jim Henson Company.
A private service is being planned.
