- Henry Watkins, a captain in the Royal Artillery, obtained a British patent for a range finder in 1876. The instrument was soon adopted for service in Britain, and tested and found satisfactory by the U.S. Army in 1879. J. J. Hicks was a leading meteorological instrument maker in London. This is the model for Watkins' American patent issued in 1879. The inscriptions read "WATKINS Field Range Finder -- J. HICKS MAKER, 8 Hatton Garden, London" and "No. 12."
