Senior Judge M. Margaret McKeown of the U.S. Court of Appeals for the Ninth Circuit talks with David F. Levi about McKeown’s new book, Citizen Justice: The Environmental Legacy of William O. Douglas—Public Advocate and Conservation Champion.

U.S. Supreme Court Justice William O. Douglas was a giant in the legal world, particularly as the longest-serving justice from 1939 to 1975. His most enduring legacy, however, is perhaps his advocacy for the environment. In a way unthinkable today, Douglas ran a one-man lobby shop from his chambers at the U.S. Supreme Court, bringing him admiration from allies in conservation groups but raising ethical issues with his colleagues. He became a national figure through his books, articles, and speeches warning against environmental dangers. Douglas organized protest hikes to leverage his position as a national icon, he lobbied politicians and policymakers privately about everything from logging to highway construction and pollution, and he protested at the Supreme Court through his voluminous and passionate dissents.
