PRINCETON — While none of Bureau County’s one-room schools had what would be considered a large enrollment by modern standards, some were even smaller than others.

Virgil Gross was able to attend the Prutzman School only through the third grade. After that, he said it closed because there were only three students in the school.

“It ended up my brother and the neighbor girl, Gladys Isaacson, and myself were the only three kids in the school, so they closed it,” Gross said. “That’s when we went up to the school on the hard road.”
