Old Naval Observatory
23rd and E Sts., NW, Washington, DCBetween 1844 and 1861, the Naval Observatory, under the leadership of Matthew Fontaine Maury, became widely known as a world center for advances in oceanography and navigational information. As the father of modern oceanography, Maury made his greatest contributions to science during these years.
The U.S. Naval Observatory evolved from the Depot of Charts and Instruments, which was established by the Secretary of the Navy in 1830 to maintain and check the accuracy of nautical instruments, charts, and books. In September 1838, the Depot began to conduct continuous astronomical observations, and thus laid the foundation for the permanent establishment of a naval observatory.
Shortly after Lt. Matthew Fontaine Maury became Superintendent of the Depot in July 1842, Congress authorized the Secretary of the Navy to contract for a suitable building, at a cost not to exceed $25,000. Although an astronomical observatory was not mentioned in the act, the site on the hill at 23rd and E Streets, NW., and the plans for the structure, were selected with such a function in mind. With the construction of the Naval Observatory, the Federal Government entered into practical scientific research in an important way.
Matthew Fontaine Maury had become a naval astronomer and published A New Theoretical and Practical Treatise on Navigation in 1836. As Superintendent of the Depot, his work on winds and currents, extremely important in the days of sailing ships, led to the issue of Wind and Current Charts and Sailing Directions in 1847. In 1853, Maury represented the United States at an international congress in Brussels and convinced the participating nations to adopt this uniform system for recording oceanographic data.
In 1854, Me Depot became the United States Naval Observatory and Hydrographical Office. The following year Maury published The Physical Geography other on Sear, the first textbook of modern oceanography. His association with the Naval Observatory ended on April 20, 1861, when he resigned to follow his native Virginia into the Confederacy.
Maury's contributions to oceanography and navigation were recognized during his lifetime, and are still recalled. The Navy Oceanographic Office charts still mention their debt to this man. The simple brick observatory building, enlarged since Maury's day, now provides offices for the Potomac Annex of the Navy's Bureau of Medicine and Surgery.
