Two pioneering pubcasters in Philadelphia, John B. Roberts and Bruce Harrison Beale, died on the same day, March 8 . John B. Roberts, one of the founding directors of WHYY-FM/TV in 1957, died of a spinal infection at his home in the retirement community of Rydal Park in suburban Philadelphia. He was 94. In 1953, Roberts had founded the Temple University public radio station, WRTI-FM, now an outlet for classical and jazz music, and taught communication at the university from 1946 to 1988. “When I was an undergrad at Temple in the 1970s, “WRTI was staffed and managed by students,” said Temple faculty member Paul Gluck, who served as station manager of WHYY-TV from 1999 to 2007.
