The mathematical instrument-making business founded by John Troughton Senior in London in 1756 was subsequently continued by his nephews, John and Edward Troughton. After John died Edward took into partnership William Simms who also came from an instrument-making family. The firm of Troughton & Simms expanded to produce a wide range of scientific instruments including levels, theodolites and astronomical equipment.
The company was involved in a notorious lawsuit in the 1830s brought against the astronomer Sir James South by Troughton & Simms concerning an equatorial telescope which they had constructed for him. South claimed this was defective and refused to pay. After much wrangling the case was eventually won by Troughton & Simms, but later South reduced the telescope to pieces and advertised it for sale.
The firm continued to trade until 1922 when it was bought out by T. Cooke & Sons Ltd of York.
