John Henson, the 48-year-old son of late Muppets genius Jim Henson, died of a "sudden massive heart attack" on Friday.

Henson's death was confirmed by The Jim Henson Company on Saturday, which posted the news of his passing to the company's official Facebook page.

Henson, like his father, Jim, and mother, Jane, was a puppeteer. His credits include work on "The Muppets' Wizard of Oz," "It's a Very Merry Muppet Christmas Movie," "Muppets From Space," and "Muppet Treasure Island." He was best known for being puppeteer behind the larger-than-life character "Sweetums."

Henson is survived by daughters Katrina and Sydney, and wife Gyongyi, as well as siblings Lisa, Cheryl, Brian, and Heather. A private service is currently being planned.
