History
The database used to construct the WDS originated at Lick Observatory, where it was used to construct the Index Catalog of Visual Double Stars, published in 1963. In 1965, under the initiative of Charles Worley, it was transferred to the Naval Observatory. It has since been augmented by a large number of measurements, from Hipparcos and Tycho, speckle interferometry, and other sources.
