Description: ANTIQUE MAGIC LANTERN SLIDE DR. JOHN BRASHEAR-WAS AN AMERICAN OPTICIAN AND TELESCOPE MAKER BORN IN 1840/BROWNSVILLE PADIED IN 1920 Starting in 1880, Brashear dedicated his time to manufacturing astronomical as well as scientific instruments and conducting various experiments. He notably developed an improved silvering method, which would later 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. A crew demolishing his factory found a time capsule that became an object of dispute.SEE ALL PHOTOSPLEASE SEE MY OTHER LISTINGS INCLUDING MORE GLASS SLIDES.
