(Lewis), painter to the French king, and professor of the academy of painting, distinguished himself by his art; and died at Paris in 1674, aged 65. There are three of his pictures in the church of Notre Dame.—He left two sons who were admired for their skill in painting. The elder, who is well known under the name of Bon Boullon, was first instructed by his father; after which he went to perfect himself in Italy, and for that purpose the king allowed him a pension; at his return, he was made professor of the academy of painting. Lewis XIV. employed him in adorning several of his palaces; and there are a great number of his pictures at Paris. His talents for copying the pictures of the great Italian masters were so very extraordinary, that he frequently deceived the greatest judges. He died in 1717.—Lewis Boullon's brother, after being also instructed by his father, gained the prize of painting at 18 years of age; upon which he obtained the king's pension. He set out for Italy at his brother's return, and acquired great skill in designing and colouring. At his return to Paris he was much employed; and at length became director of the academy of painting, knight of the order of St Michael, and first painter to the king. Louis XIV. allowed him several pensions, and raised him and his posterity to the rank of nobility. He embellished the church of the Invalids, the chapel of Verailles, &c., and died at Paris in 1733.
