Doug Pledger, a popular announcer at classical music station KKHI for several decades, died April 7 at age 89, the Chronicle reported today. Longtime KKHI announcer Al Covaia told the Chron that even though Pledger was known for classical music, he had a diverse broadcasting career, a variety of interests and a sound business sense. He broadcasted Cal basketball games for a while, ran an ad agency, was a tax attorney, and at one point owned a San Mateo-based radio station. He’s seen here in a 1950s promotional photo from KNBC San Francisco (now KNBR) where he played polka and marching band music. (Photo credit: Chronicle)
