A collection of features and graduate profiles covering Harvard’s 375th Commencement.

Under clear skies and a hot sun, thousands of alumni and friends from around the world converged on campus on June 5 for the fifth annual Harvard Alumni Day.

The celebration honored graduates from every School and class year. Held in tandem with the Harvard and Radcliffe College reunions and a range of other alumni events, the day drew more than 9,000 participants, with a main program that featured musical performances, the conferral of Harvard Medals, remarks from President Alan Garber ’77, Ph.D. ’82, and a keynote address from Jonny Kim, M.D. ’16, a decorated Navy SEAL, physician, and former NASA astronaut.

The main program opened with the traditional alumni parade from the Old Yard to Tercentenary Theatre, led by the chief marshal of alumni, Alejandra Casillas ’01, M.D. ’05, and the two oldest alumni in attendance, Linda Cabot Black, Radcliffe ’51, and William “Bill” Dubey ’46.

After Sheriff of Middlesex County Peter J. Koutoujian, M.P.A. ’03, called the program to order, outgoing Harvard Alumni Association (HAA) president Will Makris, Ed.M. ’00, reflected on the support he received from faculty, his husband, and friends during his time at Harvard.
