To celebrate the 100 year anniversary of the dedication of the Allegheny Observatory, there will be a screening of the new film “Undaunted,” which stars the Allegheny Observatory and the two men who changed astronomy and physics with their discoveries there.

“Undaunted” tells the story of the Allegheny Observatory and the contributions made by its original operators John Brashear and Samuel P. Langley, despite the many setbacks and challenges they faced.

The free screening will begin at 8 p.m. in Observatory Hill on Saturday.

“It’s really about shedding a positive light on Pittsburgh,” said filmmaker Dr. Dan Handley noting that most people, even in the Observatory Hill neighborhood, don’t realize what a “powerhouse of astronomy Pittsburgh has been for over 100 years.”
