The Nautical Almanac

The Nautical Almanac, first published in 1766, contained new lunar tables from German mathematician Tobias Mayer. Mayer’s tables enabled navigators to determine longitude with an accuracy within a few nautical miles. After Mayer's death, the English Board of Longitude awarded his widow a longitude prize.
