Sir Harold Spencer Jones KBE FRS

Spencer Jones's astronomical work extended over a range of subjects. He specialised in positional astronomy, particularly the motion and orientation of the Earth in space. He also studied the motions of stars. He travelled to Minsk in Eastern Europe in 1914 to observe a total solar eclipse, departing during peacetime but returning after the start of the First World War. In 1922 he travelled to Christmas Island in an attempt to observe a total solar eclipse, intending to verify the deflection of the light of stars by the Sun that had been seen during a 1919 eclipse, but cloud defeated the attempts. In 1951, the Institute's highest award, the Gold Medal was named in his honour and continues to be awarded by the Institute to those who make outstanding contributions to navigation.
