There is no bit in the Post Gazette yet. Here is the story from KQV's website. (courtesy of Frank Gottleib)
Longtime KQV listeners may remember the voice of Mark Schaefer
Otto "Mark" Schaefer, who was a newsman at KQV from 1966 until the early 90's, died early Friday at the age of 84.
A native of New York City, he was once a batting practice pitcher for the Giants. Schaefer served in the Army Air Corps during World War Two. After his discharge, he began his broadcast news career at stations in Alabama, and eventually worked his way to Pittsburgh, where he was one of the original newscasters at WIIC-TV. He left WIIC, which is now channel 11 WPXI, to work at KQV.
Mark Schaefer is survived by 5 children and their families.
There will be no visitation. Funeral services will be private.
This audio of Mark is from my KQV website. (1975 during the Joey Reynolds era)
