NYTimes Obit for Joseph Sax '59, Environmental Law Pioneer

From The New York Times:

Joseph L. Sax, a legal scholar who helped shape environmental law in the United States and fuel the environmental movement by establishing the doctrine that natural resources are a public trust requiring protection, died on Sunday at his home in San Francisco. He was 78.

Nixon signed the Clean Air Act and legislation creating the Environmental Protection Agency, a year after the Council on Environmental Quality was created in the executive branch.
