Charles Francois Beautemps-Beaupre, a French hydrographer, born at Neuville-au-Pont, near Ste. Menehould, in 1766, died in 1854. He studied engineering and geography at the depot of marine charts and plans, of which his cousin Buache was the chief. At the early age of 19 he was made a government engineer, and received a commission to revise the charts of the "Neptune of the Baltic." He was rapidly promoted, and in 1791 acted as first hydrographer to the expedition sent out under D'Entrecasteaux to search for La Perouse. He made a very accurate and valuable set of charts of all the regions visited by the fleet. On his return in 1796 he completed his Atlas de la Baltique, begun some time before, and at the order of the government prepared a general hydrographic chart to be used by the French expedition then about to circumnavigate the globe. He was now promoted to the position of assistant to the chief of the marine department, and for six years constantly labored in connection with the surveys undertaken by this branch of the service. He made during this period many of the most valuable of the French charts - among them those of the E. coast of the Adriatic. In 1810 he was chosen a member of the institute.

In 1811 he made valuable hydrographic surveys of the coast near the mouth of the Elbe; and the German engineers recognized his service to science by making him in 1816 a member of the royal society of Gdttingen. In 1814 he was appointed chief of his department. In 1815 he made a complete survey of the coasts of France, one of the most valuable works of his life. The works above named are those by which he is best known; the remainder of his life was devoted to their constant revision and improvement, and to the duties of his department. He also edited Le pilote francais, the sixth volume appearing in 1844. He was called in England "the father of hydrography.'"
