Judith Nelson, 72, Pioneering Soprano Of Baroque Revival

Beginning in the late 1970s, her dozens of recordings with William Christie, René Jacobs, Christopher Hogwood, John Eliot Gardiner, Emma Kirkby and others were standard-setters. She was also a founding member of San Francisco’s Philharmonia Baroque Orchestra, and she performed regularly in the Bay Area until she was 60, her pure voice remarkably intact.
