World War Two veteran Eileen Younghusband – who helped track down launch sites for German V2 rockets after D-Day – has died in hospital in Cardiff at the age of 95.
Ms Younghusband wrote an award-winning book about her experiences as part of the Women’s Auxilirary Air Force (WAAF) during the Second World War.
Aged only 19, Ms Younghusband worked at Bletchley Park, where German secret codes were cracked.
After the 1944 invasion of France by the Allies, she travelled to Belgium with a small team of women, using her mathematical skills to locate mobile launchers for V2 rockets.
Carwyn Jones, First Minister of Wales, tweeted a tribute to Ms Younghusband.
"Very sad to see that Eileen has died. A lovely lady and a real character. She will be sorely missed," Mr Jones said.
In more recent times, Ms Younghusband campaigned against cuts in adult education and was awarded the British Empire Medal for her work.
Ms Younghusband’s latest book, One Woman’s War, was published in 2011 and won the People’s Book Prize.
It depicts her journey through the war and the secret work behind Britain's wartime radar network.
To help future generations understand the consequences of war, she rewrote her wartime memoirs with younger audiences in mind.
Speaking to WalesOnline earlier this year, she said: “It is my hope that all children will read my book. I think it is really important to engage with young people about World War Two,
“World War Two was a pivotal moment in our history. I feel my book helps to make a sense of the insecurities we all face at the moment.
“In truth I am not going to be around forever but if my story can live on from generation to generation this will be wonderful."
