content: Edward Brown (1834-1905) was an Englishman who landed in New York in 1858, moved to Philadelphia, opened a small shop, and produced the first pyrometer of American design. He won a Centennial Medal in 1876, and a John Scott Medal from the Franklin Institute in 1897. The firm became Edward Brown & Son in 1905, The Brown Instrument Co. in 1910, and a division of Honeywell in 1934.
label: Description
content: To avoid defects inherent in thermal expansion pyrometers, thermo-electric instruments were introduced. This example is of that sort. The (now missing) cover was marked "Brown Electric Pyrometer / Brown Instrument Co. / Philadelphia, Pa."
