A prime meridian. Established by Sir George Airy. By 1884, over two-thirds of all ships and tonnage used it as the reference meridian on their charts and maps. In October of that year, 41 delegates from 25 nations met in Washington, D.C. for the International Meridian Conference, and selected the meridian passing through Greenwich as the official prime meridian.
