Cyril Francis Caunter (22 March 1899 in Ilford, Essex – 10 April 1988), was a British aviation historian and author.
He was the son of Lionel George Caunter from Dittisham, Devon and Elizabeth Gertrude Einhauser from St Pancras, Middlesex.
The Caunter engine performed well at Woodley with Miles, who proposed a company to produce it, to install in an aeroplane that would be sold in large numbers like Ford cars.
Phillips & Powis increasingly concentrated on military training aircraft production at Woodley from the late thirties and the Caunter engine was put aside.
The National Film Board of Canada produced Full Circle, a vignette about Caunter returning to flight and college at the age of eighty.
Caunter mentions in his 1969 unpublished autobiography that his space novels were inspired by those of H. G. Wells but were written too soon to be popular in the 1970s.
