Canada: Thomas Pocklington Ltd. made and repaired surveying instruments in Toronto between 1925 and 1992. It was one of the few Canadian firms producing precision instruments before WWII. Thomas (b. 1882), the founder, was trained as an instrument maker in the U.K. He moved to Toronto in the early 20th century and worked for Consolidated Optical Co. until he started his own business in 1925. From that time until 1940 the firm occupied a location near what is now the Eaton centre; from 1940 to 1953 the firm occupied 30 Bridgman Ave (presently Tarragon Theatre); from 1953 to 1992 they occupied 208 Weston Rd. The CSTM has the Brightly circular dividing engine (CSTM ARTIFACT # 1992.1776) purchased by the firm in 1940. Thomas was succeeded by his son William, who was succeeded by his two sons John and Ronald. Very little is known about the small precision instrument industry in Toronto in the late 19th and early 20th century. Our growing collection of archival material and artifacts related to Pocklington, one of the leaders in that community, provides a more complete picture of this history.
