Inscription.  This building once housed the U.S. Naval Observatory (1844-1893), the workplace of Navy scientists whose skill and perseverance made this institution one of the finest astronomical laboratories in the world. Here its superintendent, LT Matthew Fontaine Maury, wrote the first textbook on oceanography. As father of this science, Maury published among other works the Wind and Current Charts that revolutionized ocean travel, earning himself the title "Pathfinder of the Seas." In the east wing residence he mapped the under-ocean route for the first transatlantic telegraph cable. In 1877, astronomer Asaph Hall, using the world's largest telescope, discovered the two moons of Mars—Deimos and Phobos—during what has been termed the Observatory's "Golden Age." Through the 1870s and 1880s teams of this institution's astronomers traveled throughout the globe to study solar eclipses and transits of the planet Venus. The U.S. Naval Observatory's master clock, calibrated by celestial observations, became the time standard for the nation. After the Observatory moved to its current location on Massachusetts Avenue in 1893, the building became home
