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 identified the importance of biological diversity in creating 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.
