Women's History Month: The Women of Medmenham

Women's history month
This Women’s History Month, the National Collection of Aerial Photography (NCAP) is privileged to introduce you to a small selection of some of the many women who contributed to the vital photo intelligence work undertaken at RAF Medmenham, home of the Allied Central Interpretation Unit (ACIU).
Women’s uniformed services had existed during the First World War, but were disbanded shortly after the Armistice. They were reformed with volunteers just before the outbreak of the Second World War, and by late 1941 women were being actively conscripted.
Some of the earliest volunteers who joined the Women’s Auxiliary Air Force (WAAF) became plotters in operations rooms, a high-pressure role tracking the live positions of enemy and RAF aircraft. Some of these went on to become photographic interpreters (PIs), while the first dedicated women PIs were actually recruited and employed as civilians, before being commissioned into the WAAF.

a growing service
The number of PIs – men and women – continued to grow through the first months of the war, as the vital importance of photographic reconnaissance became increasingly understood. When they were moved from their initial home in Wembley to RAF Medmenham (based at Danesfield House near the village of Medmenham) in April 1941, one third of the total PI personnel were WAAF commissioned officers.
They came from a wide range of backgrounds. In age some were only just out of school, while two (Dorothy Garrod and Lady Charlotte Bonham Carter) had volunteered during the First World War. There were teachers, photographers, academics and students; the niche natural attributes required to be a successful PI meant that they were an eclectic lot.
Regardless of whether they were a typist or the daughter of the prime minister (Sarah Churchill), the photographic interpreters all went through intensive training. The PIs learned basic scaling, recognition, identification and measurement – all key skills for their work. A crucial element was learning how to view pairs of images in three dimensions using a stereoscope.

Leading the Way
Women were not just at Medmenham to make up the numbers, several went on to head up various of the different interpretation sections at Medmenham, although they were often joined in charge by a male officer. The remarkable Constance Babington Smith – who had a background in aviation journalism – was one of the few to head a section on her own.

By March 1945, WAAF numbers at Medmenham outnumbered RAF numbers 719 to 684; across all services there were 794 women to 908 men, with the WAAF being the single largest service group. Women PIs contributed to some of the most significant operations of the war, from the Normandy Landings to Operation Crossbow combatting deadly German V Weapons.
To celebrate their achievements, this Women’s History Month we will be publishing a short series of articles spotlighting just five of these remarkable women: Constance Babington Smith, Ursula Powys-Lybbe, Dorothy Garrod, Lady Charlotte Bonham Carter and Sarah Churchill. NCAP is responsible for maintaining their legacy through our collections, and we are privileged to bring you their stories.
We are indebted to Christine Halsall’s Women of Intelligence - among many other books and other sources - for providing much of the information we will be discussing during this series.
