Benjamin Cole

Benjamin Cole of 136 Fleet Street, London
1695-1766[1]
In 1782 brothers John and Edward Troughton took over Cole's workshop.
Edward Troughton (1756-1835) had learned his trade from his uncle, John Troughton, a leading instrument maker in London; he also worked with his equally talented brother, also named John.
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.
