1957
Lawrence Freed ’57, P ’00
Lawrence Freed traveled across the U.S. four times (and Canada once), and has visited almost all of the country’s national parks, monuments, and historic sites, and witnessed tribal ceremonies — experiences that inspired his interest in the environment. He has been dedicated to the city of Worcester, where he has volunteered for several environmental organizations and served on government entities focused on conservation. Lawrence also co-founded nonprofits including the Regional Environmental Council and Green Hill Park Coalition, and has testified on Beacon Hill and in front of local environmental boards and commissions. He also received the Region I U.S. EPA Merit Award.
1963
Duncan L. Clarke ’63

Duncan L. Clarke has published his second novel, Murder on the Appalachian Trail. He has hiked the 2,200-mile trail from Georgia to Maine twice with his German Shepherd and is a 50-year member of the Appalachian Trail Conservancy.

Duncan is professor emeritus of international relations and former director of the United States Foreign Policy Program at American University’s School of International Service in Washington, D.C. He has authored numerous articles and five books on U.S. defense and foreign policy.
Ross E. Heller ’63

Ross E. Heller has married Cheryl A. Adamscheck, a 1968 graduate of the University of Oregon. Ross and Cheryl celebrated a dual wedding: They were married on March 1 at the Calvary Episcopal Chapel in Seaside, Oregon, by the Rev. David Sweeney, and then on May 4 were wed at their home in Chevy Chase, Maryland, by Rabbi Eric Abbott, spiritual leader of the Bethesda Jewish Congregation. A nice crowd of friends and family came to both events.
Margot Overington ’63
Margot Overington’s dedication to environmental justice began when she attended a 1973 environmental conference and met E.F. Schumacher, the author of Small Is Beautiful; C.J. Swet, who invented solar panels for cooking in rural India; and scientists from Woods Hole, Massachusetts, who were working on both windmills for electricity and fish farming within a small, controlled ecosystem. She shared the urgency of changing from oil and gas to renewable resources with her Quaker Meeting and, with the help of St. Mary’s University, Halifax, they held a weekend conference called “Energy and Peace.” The long-term results of the conference included the Woods Hole scientists being invited to test the viability of using wind energy on Prince Edward Island. The Province of Nova Scotia began experimenting with tidal energy in the Bay of Fundy, and fellow Clark alum Susan Holtz ’71 was invited to join discussions on nuclear power in Ottawa. Margot moved to British Columbia and is still active in environmental activism. Her current interest is affordable housing.
1968
Daniel Ranalli ’68
Daniel Ranalli is a visual artist with a 45-year body of work engaging with environmental issues. His exhibition “Whale Stranding” traveled to the Ilulissat Art Museum in Greenland after a nine-month stay at the New Bedford Whaling Museum and will travel to additional venues in 2025. His most recent work, “The Garden Series,” is a dystopic vision of what is going on with our environment and uses figures from art history to represent the expulsion from the Garden of Eden. Daniel and his wife, the artist Tabatha Vevers, divide their time between Cape Cod and Tucson, Arizona. Daniel also sits in as an occasional vocalist with the band Sensible Shoes.
Donna Hamil Tamlan, M.Ed. ’68
Donna Hamil Tamlan is a psychotherapist and visual artist. In the past decade, her art’s focus has been about keeping the Earth livable. Her ongoing participatory art project is “The Snowball Effect,” where she asks people at public events to commit to one new action to help the environment. “Clarkies, of course, participate with great enthusiasm,” Donna wrote. The person writes their “eco-pledge” on a plastic scrap cut from detergent bottles; Donna tacks the pledges onto a giant fish form to create a living piece of art. They have been displayed at several locations. “Thousands of eco pledges have been collected over the years, and hopefully as many hearts and minds have been impacted as well to benefit our beautiful planet.”

William Riebsame Travis, Ph.D. ’81
William Riebsame Travis recalls working with Geography Professor Robert Kates on the first NSF-funded research linking climate and society. He writes: “In that first project, called CLIMPOP for climate and population, grad and undergrad students studied the history of climate impacts in the Tigris-Euphrates Valley, the African Sahel, and the U.S. Great Plains. I got assigned to the Great Plains and the next summer found myself on puddle-jumper commuter flights across the Plains, from Boulder, Colorado, to Miles City, Montana, to Williston and Fargo, North Dakota, collecting data on farm economics through historical droughts (1910s, 1930s, 1950s and 1970s), to test Bob’s hypothesis about adaptation that, over time, lessened climate impacts. We presented our results at the first Climate and History Conference at the University of East Anglia in the UK, my first trip outside the U.S.” William still works on climate and society research at the University of Colorado and maintains a website of Bob’s work on climate, hazards, and sustainability, at www.rwkates.org

In memoriam
Correction: Please note that an earlier version of the list of alumni deaths, Passings (appearing below), mistakenly included the name of Daniel J. Greenwald ’86. Mr. Greenwald is very much alive. We sincerely regret the error.
John H. Flavell,
M.A. ’52, Ph.D. ’55

John H. Flavell, M.A. ’52, Ph.D. ’55, a preeminent figure in modern developmental psychology who founded the field of metacognition, passed away on March 13, 2025, at age 96.
Among his many contributions, Flavell’s treatise on the work of Jean Piaget effectively introduced Piaget, and the structuralist approach to children’s thinking, to American psychology. So clear and compelling was Flavell’s presentation that the Piagetian approach quickly became the dominant paradigm in cognitive development, and it remains a powerful force in that field.
David G. Hayes ’57
David G. Hayes ’57 passed away on June 8, 2025, in Greensboro, North Carolina.

Stephen Provencher ’64

Stephen Provencher ’64 passed away on July 10, 2025, in Oakville, Ontario, Canada, after a long battle with cancer. He is survived by his beloved partner and wife of 42 years, Carola Koitz.
Stephen was born on November 3, 1942, in Worcester. He received his bachelor’s degree in chemistry from Clark and earned his Ph.D. in chemistry from Yale University.
Clark University was always close to his heart. Stephen felt the University transformed his life, allowing him to be rigorously challenged in the sciences. He and Carola endowed a scholarship fund in his name for students in need.
Besides science, Stephen had a passion for car racing and won multiple trophies in the Formula Ford series. Through an automotive internship, he learned how to repair his own racing cars.
In 2000, Stephen and Carola moved to Oakville, Ontario, Canada, where they started LCModel, Inc. A popular software program used for interpreting diagnostic medical research data, the technology has been sold worldwide for more than 20 years and is utilized in conjunction with MRI, PET, and other spectroscopy-based medical studies. Stephen retired from the company in 2022.
Stephen and Carola were benefactors of the arts in Canada and enjoyed traveling the world.
