From the Lawrence Daily Journal-World for May 23, 1972:

Yesterday’s Commencement was the 100th for Kansas University, and apparently even the weather decided to celebrate the centennial. Two blares from the KU steam whistle had signaled to graduates and their guests that incoming rainy conditions were necessitating a mass exodus from Memorial Stadium to Allen Fieldhouse. The fieldhouse was then packed nearly to the rafters as more than 3,000 graduates received their diplomas to the cheers of thousands of relatives and friends. KU Chancellor Laurence Chalmers praised the graduates for their motivation and participation in “more changes of both academic and extra-curricular policies and procedures than any other class in many decades.” He encouraged the graduates to apply themselves “with as much energy, ability and conviction” in the world outside college but warned them, “Do not despair over the slow progress of your efforts, over the inertia in the system,” as many worthwhile changes throughout history had been the result of continuous effort by many people.
