The National Archives Comes Alive: Young Learners Program: Meet Ruth Patrick

Ruth Patrick, botanist, limnologist, and recipient of the National Medal of Science, was a pioneer in freshwater ecology who broke gender barriers in the early 20th century. She gained world-renown when she developed what is known as the “Patrick Principle,” which identifies that the importance of biological diversity creates a more balanced river ecosystem. Dr. Patrick has advised five Presidents of the United States on water quality and pollution.
Ruth Patrick is portrayed by Carol Spacht of American Historical Theatre.
