See also Dame Eileen Younghusband for the researcher and teacher on social work. Eileen Muriel Younghusband, BEM (née Le Croissette; 4 July 1921 – 2 September 2016) was a filter officer in the Women's Auxiliary Air Force in World War II. She worked in the filter room, a top-level British air defence hub which assessed radar reports in order to give air raid warnings. Later, while posted to Belgium, she was part of a team of mathematicians who alerted Allied forces to the location of V-2 rocket launch sites. Younghusband completed a university degree at the age of 87 and subsequently published three books about her wartime experiences: two memoirs and one children's book. Eileen Le Croissette was born in London in 1921. She left school shortly after her 16th Birthday. She then worked in the Head Office of the Scottish Provident Institution in London, who provided life assurance. She worked as an Au Pair in France after her German teacher suggested she gain experience in speaking French and German to help set up his new business, the 'School Travel Service'. Eileen Le Croissette joined the Women's Auxiliary Air Force (WAAF) in 1941 at the age of 19, and was trained at RAF Innsworth, near Gloucester, and RAF Leighton Buzzard. Commissioned as an assistant section officer in November 1941, and promoted to section officer in October 1942, she was posted to 10 Group Fighter Command at RAF Rudloe Manor, Corsham, near Bath, where she was deployed as a filter officer. Following VE Day she was seconded to the Breendonk concentration camp, where she acted as a guide and interpreter (she was a fluent French speaker), relaying to RAF personnel the realities of war. She resigned her commission on 14 December 1945 and moved into hotel work. Younghusband graduated from the Open University at the age of 87, and wrote two volumes of memoirs, Not an Ordinary Life (2009) and One Woman's War (2011), the latter dealing more specifically with her wartime experience. She later adapted her books for children and in 2016, just weeks before her death, her children's book Eileen's War was published. Younghusband campaigned on health and education issues, such as cuts to adult education, and she was awarded the British Empire Medal in the 2013 New Year Honours for services to lifelong learning. Britain's Got Talent finalist Nathan Wyburn created a portrait of Younghusband from wartime images of her to commemorate her World War II work. A life-size statue of Younghusband as a young WAAF officer stands in a replica filter room at the Battle of Britain Museum at Bentley Priory.
