Distinguished Scientist and Curator Emeritus,

National Museum of Natural History

Dr. W. John Kress is Distinguished Scientist and Curator Emeritus at the Smithsonian’s National Museum of Natural History. He was Curator of Botany for over thirty years and formerly served as the Interim Under Secretary for Science at the Smithsonian and Director of Science in the Grand Challenges Consortia at the institution. Dr. Kress received his education at Harvard University (B.A., 1973) and Duke University (Ph.D., 1981), where he studied tropical biology, ethnobotany, evolution, and ecology. His taxonomic work on the Zingiberales, a group of tropical plants that includes gingers, bananas, and heliconias, has taken him around the world documenting plant life and discovering new species. Dr. Kress was instrumental in developing the genetic tool known as “DNA barcoding” for plants, which allows the accurate identification of plant species using a short, universal segment of DNA sequence. He was one of the founders of the Earth BioGenome Project and served as Co-Chair for five years. His research has been focused on plant evolution, biodiversity conservation, and the Anthropocene. Among his over 300 scientific and popular papers are his books   Plant Conservation – A Natural History Approach, The Weeping Goldsmith, The Art of Plant Evolution, Botanica Magnifica, The Ornaments of Life - Coevolution and Conservation in the Tropics, and Living in the Anthropocene – Earth in the Age of Humans. Dr. Kress recently completed Smithsonian Trees of North America published by Yale University Press in the Fall of 2024. He is a Fellow of the American Association for the Advancement of Science and has received the Parker-Gentry Award for Biodiversity and Conservation from the Field Museum of Natural History, the Edward O. Wilson Biodiversity Technology Pioneer Award, and the Peter H. Raven Award for public understanding of science. As well as serving as Affiliate Faculty at George Mason University, he was a Visiting Scholar at Dartmouth College and the Arnold Arboretum of Harvard University.

She has appeared on numerous television and radio programs, and her Ted Talk, Why We Should Trust Scientists, has over 1,600,000 views, and is the 2025 recipient of the Volvo Environment Prize.

SHARON S. TISHER '73, J.D.

Emerita Lecturer, University of Maine

Sharon Tisher is an emerita lecturer at the University of Maine, where she has taught for 30 years: the core humanities "Civilizations" sequence and a variety of tutorials in the Honors College, and environmental law and policy courses in the Ecology and Environmental Sciences program. She has chaired the boards of the Natural Resources Council of Maine, the Maine Organic Farmers and Gardeners' Association, the Orono Land Trust, and the Urban League of Greater Hartford.

It is a 450-page searchable color-coded record of events in climate science, U.S. policy and international policy, starting in 1824. With references and web links to documents, news, and commentary, it is intended as a springboard for research, contemplation, and action. Before transitioning to academia, she practiced trial law for 15 years with Day, Berry and Howard in Hartford. She was the firm's first woman partner.
