Wren W. Wirth "was a founder and is now President of the Winslow Foundation, established in 1991 to address environmental problems. The Foundation is dedicated to increasing scientific knowledge and supports ongoing projects on the intersection of environmental and human health, population, global warming and the need for renewable energy, and advancing public understanding of these matters. Grants are focused primarily on matters concerning carrying capacity: biodiversity, habitat conservation and restoration, ecosystem services, and human population and consumption patterns, including the effects of pollution and waste.
"Born in Cleveland and a graduate of Smith College, Ms. Wirth has been involved with progressive politics most of her adult life. Her husband, Timothy E. Wirth, was a United States Congressman and then Senator from the state of Colorado from 1975 to 1993. Ms. Wirth campaigned, debated, and organized Congressional and Senate projects and inquiries during those eighteen years. She was an active member of Congressional Wives for Soviet Jewry and a leading participant in the Congressional Clearinghouse on the Future and the Environmental Study Group. She and her husband hiked and rode some of the most beautiful and remote areas of Colorado in the preparation of The Indian Peaks Wilderness Act of 1979 and the extensive Colorado Wilderness Act of 1993.
"Ms. Wirth has long been engaged with her husband in global population, climate, and environmental issues, accompanying him when he chaired the US Senate delegation to the Earth Summit in Rio in 1992, and when, as the first Undersecretary of State for Global Affairs at the State Department, he led the US delegation to the 1994 Cairo Conference on Population and Development.
"Ms. Wirth and her husband are residents of Boulder, Colorado and Washington, D.C. They have two grown children, Christopher Wirth of Boulder and Kelsey Wirth of Cambridge, Massachusetts. Both are married and have young children."
