Description
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, and a division of Honeywell in 1934.
This is the model that Brown submitted to the U.S. Patent Office in 1872. The dial is 4-inches diameter, graduated from 0 to 1500 by hundreds, and marked "PYROMETER EDW. BROWN PHILADA."
