Barry Commoner, a national enviromental leader, died this week. He was 95 years old. Commoner, a professor of Queens College in New York City, and author of many books, was well-known for his precedent-setting studies on dioxin in the environment, incineration and other environmental issues. CHEJ honored Commoner at a reception two years ago. He will be sorely missed, but his environmental legacy lives on.
