Former WBEZ sportscaster Bob Greenberg died of cancer in a hospital in Williamsburg, Va. on Monday. Greenberg, who worked at the station from 1975 to 1990, never actually watched the sports he covered, as he was blind.

Cheryl Raye-Stout, who currently covers sports for WBEZ, knew Greenberg. She said he wasn’t afraid to ask coaches the tough questions, and former Bears head coach Mike Ditka was no exception.

She said that could lead to colorful exchanges, like in 1988, after the Bears played the Philadelphia Eagles in what came to be known as the “fog bowl.”

“In the press conference, he goes ‘Mike, I think I saw as much of the game as you did.’ And Ditka responded, ‘For the first time Bob, you’re right,’” Raye-Stout said.

Greenberg, who friends say was probably best known as the “blind sportscaster” for WBEZ also worked at other stations in Chicago and around the country, including KMOX in St. Louis. For the last seven years, Greenberg was part of a weekly Saturday morning show on Zecom Radio.

Raye-Stout remembers Greenberg as engaging and opinionated.

“He knew and loved sports just as much as anyone who had sight,” she said.

According to property records, Greenberg was 67 years old.
