Gordon published an autobiography in the British Astronomical Association Journal:
A University of Surrey autobiography presentation, Guildford 2016:
Gordon has been the recipient of a number of awards from astronomical associations.
The Merlin Medal and Gift, in 1962 and in 1979
"in recognition of notable contributions to the advancement of astronomy."
An ‘outstanding contribution’ award, in 2009, from the BAA
"in recognition of his outstanding contribution to astronomy over 50 years and, in particular, his 1973 prediction of the occultation of SAO 158687 by Uranus which led directly to the discovery of that planet's ring system four years later."
The David E. Laird Award of IOTA, in 2014
"for being the Father of Asteroidal Occultations, His Role in Predictions for both Lunar and Planetary Events, and for truly Pioneering Occultation Work since the 1950's."
Trust Chairman David Bieda writes:
"Over the years the Sundial Pillar has become one of London’s iconic landmarks but unlike other monuments it serves a purpose - telling the time. Each of the six dial faces is accurate to within 10 seconds based upon Gordon’s detailed calculations then drawn and carved by Caroline Webb. The one tonne dial stone was carved by trainee stonemasons. I still remember the dial stone being raised and lowered over three days supervised by Gordon and our architect AD Mason to arrive at as an exact as possible a result. All in all an extraordinary result and a great tribute to Gordon whose name is commemorated on the brass ring at the foot of the Sundial Pillar."
