HM Nautical Almanac Office

The HM Nautical Almanac Office (HMNAO), now part of the Rutherford Appleton Laboratory, near Abingdon in Oxfordshire, was established in 1832 on the site of the Royal Greenwich Observatory, where the Nautical Almanac had been published since 1767.

In 1937 it became part of RGO and moved with it, first to Herstmonceux, near Hailsham in East Sussex in 1948, then to Cambridge in 1980. When RGO closed in 1998 HMNAO was transferred to its present location.

Leslie Crombie, a pioneer of numerical computation, was Superintendent of HMNAO from 1930 until 1936.
