The William W. Treat Lecture Series has reached thousands of participants over the years with noted civic leaders discussing key issues of the day in locations throughout the state and online. Our inaugural event in 2012 was a conversation between former US Supreme Court Justice David Souter and PBS NewsHour’s Margaret Warner. In the second Treat Lecture, Justice Souter himself interviewed US Supreme Court Justice Sandra Day O’Connor. Other Treat Lectures have featured U.S. Attorney General Merrick Garland, General James Mattis, former solicitors general Gregory Garre and Neal Katyal,  attorneys David Boies and Ted Olsen, National Public Radio’s Nina Totenberg, writer and founder of Citizen University Eric Liu, Maine Senator Susan Collins, and former New Hampshire Governor and Senator Judd Gregg, among others.
