Ralph S. Paffenbarger, 84, epidemiologist
PALO ALTO, Calif. (AP) — Dr. Ralph S. Paffenbarger Jr., a medical professor and researcher whose study of the connection between exercise and longevity influenced the modern physical fitness movement, died July 9 at his home in Santa Fe, N.M., after a long battle with congestive heart disease. He was 84.
Dr. Paffenbarger, an epidemiologist, spent several decades studying the exercise levels, illnesses and deaths of more than 50,000 people who had graduated from Harvard University or the University of Pennsylvania between 1916 and 1950.
In 1986, he published an influential study based on his data. His work showed that men who burned at least 2,000 calories a week had death rates one-quarter to one-third lower than those who did not exercise regularly.
His study also showed that the amount of additional life for people who got adequate exercise compared with those who were sedentary was one to two years.
He joined the Stanford University School of Medicine in 1977 as a professor of health research and policy, and he retired in 1993.
Jim Mitchell, 63, adult-film producer
PETALUMA, Calif. (AP) — Jim Mitchell, a pioneering pornographer who was convicted of killing the brother with whom he built the Mitchell Brothers adult-film empire, died July 12 at the ranch near Petaluma where he had lived quietly since his release from San Quentin State Prison in 1997. He was 63.
Mr. Mitchell and his late younger brother, Artie, produced “Behind the Green Door” and other adult films during the 1970s.
The cause of death was not immediately known, but foul play was not suspected, Sonoma County Sheriff’s Sgt. Mitch Mana said. Merle Lane, a relative of Mr. Mitchell’s wife, Lisa, said it appeared Mr. Mitchell had a heart attack.
In 1969, the Mitchells opened a still-running adult movie theater in San Francisco. The pair, who faced multiple arrests on obscenity charges, ultimately produced hundreds of films.
Their glory days came to an abrupt end in 1991, when Mr. Mitchell shot his brother. Jim Mitchell was carrying a rifle and a revolver when police arrested him at his brother’s Marin County home. He was convicted of involuntary manslaughter in 1992 and spent five years at San Quentin before being paroled in 1997.
