In April 2019, board members, learned society leaders, delegates, associates and other friends of ACLS gathered at a festive dinner in honor of the centennial. Guests received copies of the centennial publication, The First Century, watched the centennial film, ACLS at 100, and heard from esteemed fellows Andrew Delbanco, William Kirby, Chair of the ACLS Board of Directors, Viet Thanh Nguyen and Laurie Patton, and from MariĆ«t Westermann of the Mellon Foundation, Pauline Yu, and Nicola Courtright, vice chair of the ACLS Board of Directors.
