Robert J. Lurtsema (November 14, 1931–June 12, 2000) was a public radio broadcaster.
Lurtsema hosted the classical music show Morning pro musica on WGBH in Boston, Massachusetts, from 1971 until his death from idiopathic pulmonary fibrosis. He was known among public radio listeners throughout New England for his sonorous voice and his phrasing, which frequently included long pauses.
The long pauses, anathema to mainstream radio, were either tolerated or loved by his loyal listeners. “I’m not afraid of dead air,” he was quoted as saying. “I don’t think there’s anything wrong with a quiet spot once in a while. When I pause I’m visualizing my audience, the person I’m speaking to. I always imagine I’m speaking to someone in particular.”
