Brightly (18171897) was born in England, arrived in the United States in the 1830s, and worked as a machinist in Philadelphia before going into partnership with Heller in 1870. Within a few years Heller & Brightly were said to have done more than any other [firm] in this country of late years to increase competition in the trade, and to wake up the different makers to a sense of the many improvements that may be made in the instruments in common use. Heller & Brightly was a traditional craft workshop. And were used in every state in the union, and in several foreign countries..There were only a few employees at any one time, each could produce an entire instrument, and each was reasonably well paid. They produced some 100 instruments per year from 1870 to 1887. Annual production rose to 216 instruments in 1891, then dropped precipitously and remained at modest levels thereafter. Each instrument has a serial number, the first being #4000. The firm was incorporated in 1926, and remained in business until 1968.
