When Richard Lalli ’80MUSAM, ’86MUSAD, received the 2007 Yale College prize for Teaching Excellence in the Humanities, eight of his students came onstage to sing one minute’s worth of Handel’s Messiah—from the “Alleluja” chorus, naturally. Lalli, an adjunct School of Music professor for two decades, has won raves from undergraduates for his course in vocal performance and his leadership of the college Opera Theatre and Baroque Opera Project. On March 5, Lalli became master-elect of Jonathan Edwards College. (His term will begin next January.) His partner, Michael Rigsby ’88MD, medical director of University Health Services, will be associate master.
