When we think of the American Revolution, we picture 13 colonies squaring off against the British Crown in a spirited bid for independence. But this version of the story is only half the truth—and perhaps not even the most interesting half. In this riveting program, historian and author Richard Bell invites us to rediscover the Revolution as a world war that unleashed chaos, opportunity, and transformation across six continents—from the sugar fields of the Caribbean to the court of the King of Mysore, from refugee camps on the Canadian frontier to political uprisings in Sierra Leone and Peru—and traces the far-flung reverberations of the war through the lives of the people it displaced, empowered, or destroyed.

Richard Bell is Professor of History at the University of Maryland and author of the book Stolen: Five Free Boys Kidnapped into Slavery and their Astonishing Odyssey Home, which was a finalist for the George Washington Prize and the Harriet Tubman Prize. He has held major research fellowships at Yale, Cambridge, and the Library of Congress and is the recipient of the National Endowment for the Humanities Public Scholar award and the Andrew Carnegie Fellowship. His new book, The American Revolution and the Fate of the World, was published by Penguin in November 2025.

In partnership with the Upper Valley Walk to End Alzheimer's, Osher at Dartmouth will be offering this special lecture on the newest advancements in research. The presentation will focus on breakthroughs in early detection and diagnosis, advances in treatment, and insights into risk reduction and lifestyle modification strategies. Alzheimer's Association staff member Liz McCarthy will present virtually a summary of research findings from the Alzheimer’s Association International Conference (AAIC), which took place in July 2026. This Conference is the largest of its kind and brings together researchers, clinicians, and professionals from around the world to present new discoveries and progress in the science and treatment of Alzheimer’s and other dementia. Liz will be sharing highlights from the AAIC and describing the latest advances in dementia science, with time for questions and discussion.
Liz McCarthy has a Bachelor of Science degree from Penn State University and holds credentials in respiratory therapy and sleep medicine. She lives near Boston with her husband, Kevin, and a crazy dog named Juno; her two sons are away at college.

With carefully crafted, colorful slides, David will help us appreciate why Iranians today hate Americans even more than they hate the English. What was the path by which American hubris, ineptitude, delusions, and catastrophic miscalculations led to the present situation? What parts did oil, communists, Israelis, shahs, and an Islamic God play in the story? Join us for a spirited discussion as we weave together Persian-Iranian history with Hamlet, King Lear, and Richard III to unveil not a single error but a pattern of English greed and American inattentiveness, bureaucratic infighting, and a string of strategic blunders that allowed unnecessary crises to become a historic rupture with worldwide repercussions.
David Bisno, a retired ophthalmologist with degrees from Harvard, Dartmouth, and the Washington
University School of Medicine (St. Louis), has, for the past 33 years, developed and
presented courses on a myriad of subjects for ILEAD/Osher and for other institutes
for lifelong learning across this country and overseas. He is known for clear, fair,
nuanced presentations of provocative, complicated topics, engaging his students with
energy and enthusiasm. He looks forward to lively discussion.

At 63, Jill Chalsty boarded a ship alone, grieving her husband’s death and battling cancer. What began as a voyage around the world became far more than a trip.

Jill demonstrates how one person’s courage can create ripples that span continents.

Many people have an advance directive, but few understand how decisions are actually carried out in a medical setting. This class examines end-of-life planning in New Hampshire, including the role of advance directives and the critical importance of medical orders such as POLST and DNR. We will cover end-of-life options available in NH now, including voluntarily stopping eating and drinking (VSED). We will also cover Medical Aid in Dying (MAiD), a legal option available to roughly one-third of Americans, but not yet here in NH. We'll discuss what MAiD is, what it is not, where things stand in NH, and how individuals are working to bring this option to NH. The emphasis is on practical understanding, clear communication, and preparing for real-world decisions. This event is free and open to the public.
