Between 1872 and 1875, the university's first professor of physics William Arnold Anthony and student George S Moler (later, a professor at Cornell) installed two electric arc lamps on campus, one of which was in the Sage Chapel tower. The set-up represented many firsts, the first dynamo and outdoor electric lighting in the United States, and the world's first underground electricity distribution system. It was said to be the "first locality in America, if not the world, to have a permanent installation of electric arc lamps." The lamps were "visible for many miles around, and it excited the wonder of the inhabitants."
