The prize for winning on "Wait Wait ... Don't Tell Me!" was a custom-made voice recording of Kasell for answering machines or cellphone voice mails, and over the 16 years he was part of the show, he provided more than 2,200 recordings for contestants, according to NPR.
Quiz show co-host Peter Sagal called Kasell a “dear friend” in a Twitter post Tuesday.
“He was, and remains, the heart and soul of our show,” Sagal said.
Kassel retired from “Morning Edition” in 2009, but continued on “Wait Wait” for another five years.
Kasell, who was born in Goldsboro, North Carolina, in 1934, started in radio when he was 16 at a local radio station hosting a music program and continued his career in college at the school radio station at the University of North Carolina at Chapel Hill. His broadcasting career spanned more than 50 years in radio.
