On September 11, 2001, at the age of 45 and at the height of her professional and personal life, Barbara Olson was murdered in the terrorist attacks against the United States as a passenger on the hijacked American Airlines flight that was flown into the Pentagon. The Federalist Society established this annual lecture in Barbara's memory because of her enormous contributions as an active member, supporter, and volunteer leader. Solicitor General Theodore B. Olson delivered the first lecture in November 2001. The lecture series continued in following years with other notable individuals.
