John Allen arranges a permanent display inside Pfendler Hall on April 14. The display honors the photographic legacy of the Allen family. The camera was used by John's grandfather, J.C. Allen, who spent his entire life documenting Purdue campus activities.

In 1936, if you wanted a chart to document electrical energy consumption on a farm, you had to have it made by hand in the Agricultural Experiment Station on the Purdue campus.
