What was originally called Harvard Colledge (around which Harvard University eventually grew) held its first Commencement in September 1642, when nine degrees were conferred. Today some 1700 undergraduate degrees, and 5000 advanced degrees from the university's various graduate and professional schools, are conferred each Commencement Day.
Each degree candidate attends three ceremonies: the Morning Exercises, at which degrees are conferred verbally en masse; a smaller midday ceremony (at the candidate's professional or graduate school, or upperclass House) during which actual diplomas are given in hand; and in the afternoon the annual meeting of the Harvard Alumni Association's, at which Harvard's President and the day's featured speaker deliver their addresses.
Several hundred Harvard honorary degrees (which with few exceptions must be accepted in person) have been awarded since the first was bestowed on Benjamin Franklin in 1753. In 1935 playwright George Bernard Shaw declined nomination for a Harvard honorary degree, suggesting instead that Harvard celebrate its three-hundredth anniversary by "burning itself to the ground ... as an example to all the other famous old corrupters of youth" such as Yale.
The ceremonies shifted from late summer to late June in the nineteenth century, and are now held at the end of May. A number of unusual traditions have attached to them over the centuries, including the arrival of certain dignitaries on horseback, occupancy by Harvard's president of the Holyoke Chair (a "bizarre" sixteenth-century contraption prone to tipping over) and the welcoming of newly minted bachelors to "the fellowship of educated men and women."
Most upperclass Houses have rituals of their own. At Lowell House, for example, a perambulating bagpiper alerts seniors at 6:15 am for a 6:30 breakfast in the House dining hall with members of the Senior Common Room, after which all process (along with members of Eliot House, who have been similarly roused) to Memorial Church for a chapel service at 7:45.
