Constance Babington Smith 
MBE Legion of Merit FRSL (15 October 1912 – 31 July 2000) was a journalist and writer.
Babington Smith was the daughter of the senior Civil Servant 
Henry Babington Smith. She was educated at home at Chinthurst, 
England and in France, before moving to London in adult life. She worked for the 
milliner Aage Thasrup and also 
Vogue magazine in 
London, before venturing into journalism, with The Aeroplane magazine.
Her knowledge of aircraft took her into the 
WAAF in the 
Second World War, where she served with the 
Allied Photographic Intelligence Unit at 
Medmenham, reaching the rank of 
Flight Officer. Serving alongside was her brother, Bernard Babington Smith, who was also a photo interpreter (PI) at Medmenham,[2] whilst another fellow PI present at Medmenham was 
Winston Churchill's daughter, 
Sarah Oliver.

In 1942 she made an uncredited appearance in the Air Ministry feature film 
Target for Tonight, along with her fellow Medmenham colleague, Sqn Ldr Peter Riddell.[4]
Working on the interpretation of 
aerial reconnaissance photographs, Constance was credited with the discovery of the 
V1 at 
Peenemunde, 
Germany.
She was portrayed in the 1965 film 
Operation Crossbow by 
Sylvia Syms.
After 
VE-Day Constance was attached to USAAF Intelligence in 
Washington, D.C. to continue her work on photographic interpretation, this time in the Pacific theatre.
From 1946 to 1950 she was a researcher for 
Life Magazine. She later moved to 
Cambridge, 
England, where she converted to 
Greek Orthodoxy and become a writer and biographer. Her war memoir Evidence in Camera was in 1957 the first comprehensive narrative of British photographic reconnaissance in the Second World War. (Because published before the revelation of wartime code-breaking, this book may also have contained a measure of Cold War disinformation.)
Her cousin was the writer 
Rose Macaulay, Babington Smith writing a biography of her published in 1972.
Babington Smith was a founder director of the 
Mosquito Memorial Appeal Fund - now the de Havilland Museum Trust.
