Barraud. The first watchmaker of the family was Francis-Gabriel (1727-1795). His sons Paul-Philippe (1752-1820) and John (dates unknown) were working with their father by 1780. In 1796 he entered into a partnership with William Howells and George Jamison, to make chronometers based on Mudge’s original design. Howells, who had been Mudge’s junior worker, brought with him important technical knowledge. Alongside Barraud’s production of chronometers, a range of other clocks and watches were produced, and a major business was the exportation of plain and musical clocks to China and India. This was continued by their successors and eventually led to the establishment of a branch in Calcutta. In 1838 the chronometer maker John Richard Lund was taken into partnership and with the death of the last horological Barraud, Hilton Paul, in 1880, the business reverted entirely to the Lund family.
