Henri Robert Ekegrén (1823-1896) was a renowned Danish watch, clock and chronometer maker and watchmaker to the King of Denmark. He worked for Urban Jürgensen, Henry Golay, Joseph-Thaddeus Winnerl and Adolph Lange before setting up his own business in Geneva. In 1857, Ekegren founded together with Ferdinand Westermann a factory specializing in the production of chronometers which was sold to Edouard Koehn in 1891.
James Emmett Caldwell (1813-1881) began his career as an apprentice to a silversmith in Philadelphia. In the early 1830s, he opened his own watch and jewellery shop which became known as J.E. Caldwell & Company in 1848. The company retailed watches made by the most celebrated manufacturers, notably Ekegren and Patek Philippe.
