Note: Charles Fasoldt (1819-1889) was born in Dresden, Germany. By the mid-19th century he settled in Rome, New York, practicing the watchmaking trade, one in which he was particularly skilled. Fasoldt manufactured, exhibited, and won prizes for his eight-day watches, regulators, and pocket chronometers. After a move to Albany about 1860, where he manufactured award-winning tower clocks and astronomical regulators, he is credited with inventing a "peculiar double wheel escapement called 'Fasoldt's Chronometer'" (Derek Roberts, Precision Pendulum Clocks, France, Germany, America, and Recent Advancements, p. 208).
