"Undaunted, The Forgotten Giants of the Allegheny Observatory" tells the history of a 150-year-old scientific research facility, which is the largest astronomical observatory within the city limits of a major American city! This includes the amazing accomplishments of astronomers Samuel Pierpont Langley, James E. Keeler, and John A. Brashear, which helped the Allegheny Observatory become a leader in astronomical research and pioneer the new scientific field of Astrophysics.
