Our Partners The Medmenham Association

The Medmenham Association

At the heart of the National Collection of Aerial Photography (NCAP) lies 5.5 million images held by the Allied Central Interpretation Unit (ACIU) during the Second World War. These photographs were gathered and analysed at RAF Medmenham, based in Danesfield House, Buckinghamshire. The crucial contributions of the men and women at Medmenham during the war remain central to NCAP's ongoing mission to this day.

Military Legacy

The Medmenham Association was originally founded as the Medmenham Club in 1946. It was established to help Photographic Interpreters (PIs) who worked at RAF Medmenham during the Second World War stay connected and preserve the camaraderie they enjoyed during their service. Over the years, the Association has grown to include Imagery Analysts (IAs), formerly known as PIs, who have served in operational theaters worldwide throughout the twentieth century.

Members of the Association maintain the Medmenham Collection, a valuable archive of military aerial photographic interpretation and imagery analysis. This collection stretches from the First World War to the end of the Cold War. Elements of the Medmenham Collection are displayed at the Military Intelligence Museum at Chicksands, the Muckleburgh Collection near Cromer, and the Imperial War Museum at Duxford.

Preserving Heritage

As a living memorial to the military personnel involved in photographic reconnaissance and intelligence work — especially the many reconnaissance pilots and aircrew who lost their lives — NCAP is proud to maintain its relationship with the Medmenham Association. Together, we digitise and provide access to images from the Medmenham Collection. 

Website imagery

Many of the images found on the NCAP website, primarily those of PIs at work with reconnaissance imagery, are courtesy of the Medmenham Collection and this ongoing partnership.

This includes our ncap.org home page cover image, a larger full copy shown below, which showcases a leading member of the Operation Crossbow team working out of RAF Medmenham, Flight Officer Nora Littlejohn.

Additionally, our key image on our Air Photo Finder is one of the Photographic Interpreters of Z Section on the terrace of Danesfield House at the close of the Second World War.

IN THIS SECTION

A large modern, multistorey building is the focus of the image. It is primarily made from glass sheets, with white panelling between them. Our view is partially obscured by large, low bushy trees, which are spaced in between areas of grass. Decorative paving is laid directly in front of us and leads to a low, sweeping glass entranceway.

National Archives and Records Administration

In 2017, NCAP began a partnership with NARA to copy its extensive holdings of aerial photography, with a particular focus on images from the Second World War.

The city of Edinburgh, as seen from Calton Hill. The bright blue sky is crossed with stripes of cloud. In the lower half of the image buildings of varying heights and widths are clustered together, seen from above from our placement on the hill. On the left of the image is the Dugald Stewart Monument. It is composed of a circle of columns on a podium.

The University of Edinburgh - external

NCAP is committed to collaborating with staff and students at the University of Edinburgh, to further understanding of our collection and provide valuable research opportunities.

A large industrial building is the focus of the image. It has large white panelled doors which are sitting open. The main body of the building is shiny black panelling. Some areas have fencing and mesh panels. The building is partially obscured by two mature trees. There is a luminous blue sky behind the building, and some snow on the grass surrounding it.

Edinburgh Parallel Computing Centre

NCAP has been an early adopter of EIDF, providing them with our huge dataset of 30 million images to work with while accessing their critical mass of expertise in return.

A long, low profile building fills the frame. It has lots of square edges and sharp angles, and our view of it is partially blocked by spindly trees and dense, low bushes. The photograph has been taken at night, and the clear, dark blue sky glows behind the building. Three rows of windows are illuminated with orange light from inside.
