1983: The carillon becomes a 61-bell grand carillon thanks to a multi-million-dollar gift from Jerry Chambers and his wife, Evelyn. Thirteen new bells are cast and installed, allowing the instrument’s range to span five octaves, and the bells’ weight to range from 20 pounds to 5.25 tons. Sculptor Ruth Asawa creates bas-relief images of young bears for the Great Bear Bell, the largest and heaviest of all. The Campanile closes for the five-month-long installation.
The Chamberses’ endowment also provides for a permanent, full-time University Carillonist in the Department of Music – there is no position like it today at any other North American university – as well as a campanology library, practice rooms and keyboards, and a carillon festival every five years.
