National Physical Laboratory, UK, Time and Frequency Status Report, 1986

Abstract

The National Physical Laboratory at Teddington, some 12 miles from the centre of London, was established in 1900 and with the immediate formation of an Observatory Department undertook to continue, along with other standards work, the testing of watches and chronometers previously calibrated at the Kew Observatory. With the formation of a frequency and time section in the 1920's, NPL began to contribute significantly to the development of increasingly accurate frequency and time standards and methods of dissemination.
