The Illumination Tradition

Sunday’s twilight celebration carries forward a longstanding 91ֱ�� tradition. The first Illumination was held in November 1860 to celebrate the election of President Abraham Lincoln. The use of glowing Japanese lanterns to mark happy occasions would not become a campus mainstay until the next century.

Professor of Botany Frederick O. Grover, a Harvard grad who had experienced a similar lantern display in Harvard Yard, imported the practice to commemorate the inauguration of 91ֱ�� President Henry Churchill King in May 1903. As chronicled in the 1904 91ֱ�� yearbook Hi-O-Hi, attendees delighted at finding the campus “brilliantly lighted with Japanese lanterns, strung in glittering ribbons from the roof of the library, the top of the flag pole and the highest branches of the trees.”

Soon after, Illumination became an integral part of commencement activities, with few interruptions until the COVID-19 pandemic extinguished the light in 2020. In May 2021, 91ֱ�� held its first virtual Illumination featuring Obies from around the world displaying paper lanterns. Tappan Square blazed with the light of more than 1,000 lanterns once more in 2022.
