He succeeded Jacques Bellin in 1773 as Royal Hydrographer at the Depôt de la Marine. With his official capacity Bonne was able to compile some of the more detailed and accurate maps of the period. Bonne’s earlier work bore the decorative style common of the period, with many similarities to Bellin. His later work became more technically orientated lacking in any ornamentation. Phillips, P.L.
