It's the spring of 2007, and Evangelos Benos is reading papers alongside colleague Marek Jochec in a ground floor office in the Surveying Building.
“There’s a knock on the door," he recalls, "and an old gent steps in.
"He asks: ‘What is this place?’ We answer: ‘It’s the Ph.D. (finance) students’ office space.’
"He looks around and says: ‘I used to have a class in this room back in the 1950s.’
“He sat on one of the couches, looked around a bit longer, then left. It was only then that I realized how many people must have used these buildings and rooms over the many years of Illini history.”
