One Response to Denbighshire

  1. Bill Barton says:

    The chronometer maker Edward John Dent, FRAS, Associate ICE, (1790-1853) worked for some time in the mid-nineteenth century to simplify the transit telescope originally developed by Ole Rømer (1644-1710) in Denmark. Dent was motivated to make it easy for the non-astronomer to ascertaining the correct time easily. He was approached by James Mackenzie Bloxam, a barrister from Denbighshire (born circa 1814, died 1857), with an already working device. The two went into partnership with the first dipleidoscopes going on sale for two guineas (£2 2s or £2.10, equivalent to £161 at 2010 prices when adjusted for inflation) in March 1843. Bloxam appears to have been afraid of compromising his professional standing as a barrister with much of his work being published only after he died. To secure their respective rights over the device, a patent was sought by Bloxam and was granted on 20 June that year (United Kingdom Patent no. 9793). A French patent was applied for on 24 July 1844. After Dent died his stepson Frederick William Dent took over manufacture.
