John-Roger Arnold (1769 – 1843)
He was born in 1769 as the son of the watchmaker John Arnold. The craft of watchmaking he began in 1783, first apprenticing with his father and from 1792 on with Abraham-Louis Breguet. He was admitted to the Freedom of the Clockmakers Company in 1796 and became a Master in 1817. After the death of his father, John-Roger continued the company on his own until 1830. In this year he moved to Strand 48 and started a 10 year partnership with E.J. Dent; business went well during this time and the partners had the possibility to research and experiment, in particular, they investigated the influence of magnetism on chronometers. When the partnership ended in 1840, Arnold continued his work until his death in 1843.
