For twenty-five years, the Oregon Historical Society has presented the Mark O. Hatfield Lecture Series, bringing together the nation’s top historians and award-winning authors for thought-provoking evenings of history. The series began at the suggestion of Senator Hatfield and continues as a tribute to his legacy of public service and as an opportunity to share stories of the people and events that have shaped history. Past speakers include notable historians and authors Heather Cox Richardson, David McCullough, Henry Louis Gates, Jr., Jon Meacham, Cokie Roberts, and Isabel Wilkerson.
