Henry Troemner emigrated to
Philadelphia from Germany in 1836 and found employment as
a locksmith working at Girard College. In April 1840,
Troemner formed a partnership with F. Meyers and began
manufacturing scales and balances.
Troemner became the sole proprietor of the business and
in 1864 built his first factory at 22nd and Master
Streets. Troemner built precision scales for The U.S.
Mint, Custom House and Assay Offices. 1
Troemner also
built "Star" coffee mills, advertised as "the most
perfect grinder" patented in 1884. 2
The Troemner company has continued to manufacture
precision weights and scales for laboratory use and is
capable of producing "standard" weights sets. In 1960,
the company began a complete weight calibration service
in cooperation with the National Bureau of
Standards. 3
Troemner remained at 22nd and Master Streets until the
present building, once a bakery, was renovated in 1965.
Troemner currently employees approximately fifty
machinists, assemblers and
technicians.
