Carl Oglesby, 76, who led Students for a Democratic Society (SDS) as it opposed the Vietnam War but who was later expelled by a radical faction that became the Weather Underground, died on Tuesday at his home in Montclair, N.J. Oglesby, who left a military industry job and a comfortable lifestyle to join SDS, was the organization's president from 1965 to 1966. Trained as an actor and a playwright, he was regarded as one of the most eloquent spokesmen of the period.

Vito Perrone Sr., 78, a leading advocate for humanistic, regimentation-free public education and a mentor to several generations of liberal reformers who fought the tide of standardized testing, died on Aug. 24 in Cambridge, Mass. Among progressive reformers, Perrone's commitment to flexible teaching methods and his opposition to standardized tests made him the conscience of the profession in the modern era, when schools nationwide embraced standardized tests.
