Paul Phillip Barraud (born 1752) worked with his father at first until his death in 1795 after which Barraud turned his attention more towards chronometers. Using the valuable experience gained whilst working on Mudge's timekeepers with W. Howells and G. Jamieson to good effect, he became very successful. After his death in 1820 the business was continued by his sons, taking John Richard Lund into partnership in 1838 who developed the auxiliary compensation balance weight to correct for middle temperature changes.
