(AP)—Barry Commoner, a scientist and a pioneer of the environmental movement, has died in New York at age 95.
His wife, Lisa Feiner, says he died Sunday afternoon at a Manhattan hospital where he had been since Friday.
Commoner was an outspoken advocate for environmental issues and was among those who raised concerns over the effects of radioactive fallout.
He was one of the founders of a well-known survey of baby teeth in St. Louis that started in the late 1950s and showed how children were absorbing fallout from nuclear bombs that were being tested.
The survey helped persuade government officials to partially ban some kinds of nuclear testing.
