Our History

Prof. Matthew Meselson and Rev.Herbert Vetter at a Cambridge Forum on the controversial topic “Should we halt recombinant DNA research?

Cambridge Forum was originally founded by Rev. Herbert Vetter in 1967 as a program of the First Parish (Unitarian Universalist) in Cambridge to provide a safe platform from which to examine salient social issues. The Civil Rights Movement and the war in Vietnam were among the most urgent topics initially discussed. From the beginning, it brought expert scholars, writers, policymakers, and thinkers face-to-face with a public audience in a lively and engaged dialogue.

Over its 50+ year history, Cambridge Forum has presented hundreds of public programs in Harvard Square featuring such speakers as Buckminster Fuller, John Kenneth Galbraith, Marian Wright Edelman, Stephen Jay Gould, Jonathan Kozol, Lani Guinier, Paul Krugman, James Carroll, Rabbi Harold Kushner and hundreds more in respectful and meaningful discussions of potentially divisive contemporary issues. Its programs are free in every sense of the word; they are open to the public without an admission charge and based on the principles of free inquiry and freedom of speech. After laying out the topic for discussion in a brief exposition, speakers respond to the comments, questions, and concerns of the public audience. With its emphasis on dialogue, Cambridge Forum fulfills its mission of fostering civic engagement and participatory democracy and exemplifies its underlying principle that an informed citizenry will make wise decisions promoting a just society.
