FAMOUS MAKER J W NORIE & WILSON EARLY ENGLISH SEXTANT/QUINTANT CA 1850
PRESENTED is a very rare sextant, and one which will appeal to those familiar with the history of navigation. It was made by John William Norie (1772-1843), a mathematician, hydrographer, chart maker and publisher of nautical books, most famous for his Epitome of Practical Navigation (1805), which became a standard work on navigation and went through many editions, as did many of Norie’s works. His known navigation instruments are few, and normally found in museums such as the British National Maritime Museum in Greenwich, and the USS Constitution Museum in Boston.Norie began his career working with William Heather, who had in 1765 taken over chart publishers Mount and Page, and who ran the Naval Academy and Naval Warehouse in Leadenhall Street from 1795; the Naval Warehouse provided navigational instruments, charts, and books on navigation. Norie took over the Naval Warehouse after Heather’s retirement and founded the company J.W. Norie and Company in 1813. After Norie’s death, the company became Norie and Wilson, then in 1903, Imray, Laurie, Norie & Wilson. They continue in business as chart makers and were based in London until 1939, and are now headquartered in St Ives in Cambridgeshire.
