Gurley Precision Instruments, Inc.
Documenting Change: Industry and Business in Troy and Rensselaer County, NY
Historical Note: Gurley Precision Instruments traces its origin to the partnership founded in 1845 by William Gurley and Jonas Phelps. William Gurley’s brother Lewis joined the firm in 1851. The Gurley brothers bought out Phelps in 1852, and the firm became W. & L.E. Gurley. The business remained under family control until 1968, when it became part of the high-tech corporation Teledyne and the name was changed to Teledyne Gurley. In the early 1990s Teledyne sold the company, and it became Gurley Precision Instruments. The firm originally manufactured surveying, hydrological, meteorological, and other technical instruments. More recently it has manufactured electro-optical encoders used in space vehicles, aircraft mapping cameras, navigation systems, and other applications.
