Brashear, John Alfred (1840–1920) astronomical instrument-maker; born in Brownsville, Pa. A Pittsburgh steel mill mechanic by day, by night he was an amateur telescope maker. Because astronomy was beginning to attract large donations from philanthropists, in 1881 he was able to start the John A. Brashear Company, builders of astrophysical research instruments. He built George Ellery Hale's first spectroheliograph. The company was bought in 1926 by J. W. Fecker of Cleveland.
