The inspiring story of a man whose avocation as a stargazer and vocation as a millwright led to his development of lenses, mirrors and other astronomical apparatus. John A. Brashear's technological advances were later employed by astronomers in the United States and Europe. Brashear also attracted the friendship and financial support of astronomer Samuel Lagley, railroad magnate William Thaw, Henry Clay Frick, and Andrew Carnegie, who gave him $20,000 for the construction of Allegheny Observatory in Pittsburgh.
