More than 2,500 graduates and 10,000 of their friends and family members gathered under a sweltering morning sun for Washington University’s 143rd Commencement May 21. A total of 2,589 degrees were conferred, along with six honorary degrees, and three-time Pulitzer Prize-winning columnist Thomas L. Friedman delivered the Commencement address.

Liberman, chairman emeritus of Laclede Gas Company and life trustee at Washington University, as he receives a doctor of philosophy in interdisciplinary studies from the Graduate School of Arts & Sciences. At 82, (he’ll be 83 in July) Liberman is the oldest person to receive an academic degree at this year’s graduation. (It is believed that he is the oldest person to receive a doctorate from the university.)

The Class of 2004 is the first to wear the university’s new green Commencement gowns. The gowns, which have black velvet trim and the university shield on both shoulders, were designed in honor of the university’s Sesquicentennial y a faculty member.
