Maskelyne, Nevil

Nevil Maskelyne

1732-1811. British astronomer who served as Astronomer Royal from 1765 to 1811. He established the publication of the Nautical Almanac and was instrumental in providing the data for the lunar distance method of calculating longitude. Portrayed negatively in a recent book on longitude, Maskelyne's methods proved practical and efficient until the late 19th century when chronometers became common.
