Tom Fanella, president of KTEH in San Jose, Calif., for 19 years, died Monday of heart failure after fighting cancer for a year, Northern California Public Broadcasting said yesterday. He had worked for public TV stations in Pittsburgh and his hometown of Syracuse, N.Y. His stations won the top PBS Development Award six times. Despite his fundraising success and Silicon Valley’s wealth, KTEH struggled for revenue in the shadow of the nearby KQED. Fanella and KQED President Jeff Clarke arranged a merger creating NCPB last year.
