The 73-year-old, who used to host a radio show called The Comedy Hour, “was sick” and “health issues,” a building source told the NY Daily News. “I’m surprised — it’s very sad.”
Another source at the Upper West Side residence told the NY Post that Belzer had been dealing with “stomach problems,” as well as the grief since losing his wife, Sesame Street director Emily Squires, in Nov. 2012.
“He was also hurting because his wife died a couple years ago . . . they were beautiful people,” the source said.
Belzer — a graduate of Columbia University and veteran of the Air Force — and his wife wrote a 2000 book titled, Spiritual Places In and Around New York City.
