Short Answer
Early Life and Background
Yolande Elsa Maria Unternährer was born in Paris in 1911 to a Swiss father and an English mother [1, 2]. Having moved to London during her teenage years, she grew up fluent in English, French, and German, and possessed some knowledge of Italian [1, 2, 4]. Before the outbreak of the Second World War, she lived a relatively sheltered life, working as a modiste in the Highgate and Camden Town areas of London alongside her mother [2].
Recruitment and Training
Following the declaration of war in 1939, Yolande enlisted in the Women’s Auxiliary Air Force (WAAF), where she trained as a wireless operator [1, 4]. Her exceptional linguistic abilities—proficiency in English, French, German, and Italian—attracted the attention of the Special Operations Executive’s (SOE) French (F) Section, which interviewed her in November 1942 [2].
In February 1943, she was recruited into the SOE [2]. She underwent specialized training as a wireless operator, attending the wireless and security school to acquire the clandestine communication skills necessary for field operations [4]. During her training, she met Jaap Beekman, a trainee wireless operator serving with the SOE’s Dutch Section; the two married shortly thereafter [4].
Deployment and the Musician Circuit
On the night of 17/18 September 1943, Yolande Beekman parachuted into occupied France [4]. She was assigned to the Musician circuit, based in Saint-Quentin within the department of Aisne, where she served as the network’s wireless operator [1, 4].
Using the codenames Mariette and Kilt (the latter specifically for wireless transmissions), Beekman maintained regular communication with London [1, 2]. Her role was critical to the circuit’s logistics; she is credited with arranging the delivery of over 20 parachute drops containing essential weapons, ammunition, and explosives for the resistance [4].
Capture and Fate
Beekman’s operational career ended when she was arrested by the Gestapo [1]. Following her capture, she was deported to Germany [2]. She was eventually imprisoned at the Dachau concentration camp in Bavaria, where she was executed on 13 September 1944, at the age of 33 [1].
Honours and Legacy
For her service and bravery in occupied France, Yolande Beekman was awarded the Croix de Guerre and was Mentioned in Dispatches [1].
