LA PLUME, LACKAWANNA COUNTY (WBRE/WYOU) — A former Keystone College professor died over the weekend.

Thomas “Coop” Cupillari, a graduate of Keystone College class of 1960, retired in 2015 after 38 years. He was an astronomy professor and director of the college’s observatory.

The observatory opened in 1973 with Cupillari’s help and was renamed in 2000 to Thomas G. Cupillari ‘60 Astronomy Observatory.

As a professor he could explain things so clearly and so well and he always cared about his students not only about what grades they got on tests or how much they knew but as people and and again that’s one of the things that the last we admired about them so much,” Keystone College Senior Director of College Relations Fran Calpin said.

Cupillari was 81 years old.
