From Graces Guide
Benjamin Cole of 136 Fleet Street, London
1695-1766[1]
John Troughton (c.1716–1788) was in the scientific instrument trade in London, and trained his nephew John Troughton (c.1739–1807); John in his turn took a younger brother as apprentice. After this brother died, another brother, Edward (1756-1835) replaced him; Edward had learned his trade from his uncle, John Troughton.
In 1782 brothers John and Edward Troughton took over Cole's workshop.
1826 Edward Troughton took William Simms, an excellent craftsman and businessman, into partnership; Troughton and Simms manufactured mathematical instruments both large and small, and attracted customers around the world.
