This past Saturday marked the 20th anniversary of the September 11, 2001 terrorist attacks on the World Trade Center and the Pentagon. Coming on the heels of the exit of U.S. troops from Afghanistan, America’s longest war and a response to the attacks, the anniversary provided an opportunity to reflect on the legacy of 9/11.

Penn Today asked experts across the University to share their thoughts on how 9/11 transformed their field or their research, the world, or their lives. To read their comments, visit https://penntoday.upenn.edu/news/911-20-years-later.

The Office of the Chaplain and the Religious and Spiritual Life Center invited members of the Penn community to gather at the Love Statue on campus on Friday, September 10 for a 20th anniversary campus commemoration that included brief remarks by University President Amy Gutmann and Vice President for Social Equity and Community and University Chaplain Charles Howard. A moment of silence followed the remarks.
