John Brashear

John Brashear was born in Brownsville, Pennsylvania, a town 35 miles south of Pittsburgh along the Monongahela River. His father, Basil Brown Brashear, was a saddler, and his mother, Julia Smith Brashear, was a school teacher. He was the oldest of seven children. As a boy, John Brashear was heavily influenced by his maternal grandfather, Nathanial Smith, a clock repairer. When he was nine, his grandfather took him to view through the telescope of ‘Squire’ Joseph P. Wampler, who set up his traveling telescope in Brownsville. That influential view of the moon and the planet Saturn stayed with Brashear for the rest of his life. After receiving a common school education until age 15, he became an apprentice to a machinist and had mastered his trade at age 20. Beginning in 1861 Brashear worked as a millwright in a rolling steel mill in Pittsburgh. He pursued his love for astronomy at night, with the help of his wife Phoebe Stewart, a Sunday school teacher whom Brashear met in 1861 and married in 1862. Of too little means to purchase a telescope, Brashear built his own workshop from a three-meter-square coal shed behind his house and proceeded to build his own refractor. Starting in 1880, he dedicated his time to manufacture astronomical as well as scientific instruments, and performed various experiments. He developed an improved silvering method, which would become the standard for coating first surface mirrors (known as the “Brashear Process”) until vacuum metalizing began replacing it in 1932. Brashear patented few instruments and never patented his techniques. He founded “John A. Brashear Co.” with his son-in-law and partner, James Brown McDowell (now a division of L-3 Communications, and still based in Pittsburgh). His instruments gained worldwide respect. Optical elements and instruments of precision produced by John Brashear were purchased for their quality by almost every important observatory in the world. Some are still in use today. In 1892 Brashear made his second of three trips to Europe, this time providing a lecture tour. In 1898 he became director of the Allegheny Observatory in Pittsburgh, continuing in this post until 1900. From 1901 to 1904, he was acting chancellor of the Western University of Pennsylvania, now known as the University of Pittsburgh, after serving as a member of the board of trustees since 1896. Brashear also was a trustee of the Carnegie Institute of Technology and served as President of the Academy of Science and Art. John and Phoebe Brashear were active in their church as well. He served as the choir director of Bingham Street Methodist Episcopal Church, and organized the Cantata Society, composed of church choirs from Pittsburgh’s South Side. During the Panama-Pacific Exposition (1915), in which a 20″ Warner-Swasey telescope with Brashear optics was displayed, Brashear was named “the State’s most distinguished man” by Pennsylvania’s Governor Martin Grove Brumbaugh. John Brashear was admired and beloved by fellow western Pennsylvanians and international astronomers, who familiarly called him “Uncle John”. The telescope is still in use today at Chabot Space and Science Center at Oakland, California. In 1919, he suffered ptomaine poisoning (an outdated term for food poisoning), which induced a debilitating illness lasting six months. He died at age 79 at his South Side home. His body was held in state in the Great Hall of the Soldiers and Sailors Monument. His ashes are interred in a crypt below the Keeler Telescope at Allegheny Observatory, along with those of his wife. A plaque on the crypt reads: “We have loved the stars too fondly to be fearful of the night.” a paraphrase of the last line of the poem “The Old Astronomer to His Pupil” by Sarah Williams. He was survived by a daughter and several siblings. [Wikipedia]
