Noor Inayat Khan was born in Moscow in January 1914 to an Indian father, Hazrat Inayat Khan and an American mother, Ora Ray Baker.
The couple had met in the Ramakrishna Mission ashram in America.
Hazrat Inayat Khan was a Sufi preacher and musician and travelled the world taking Sufism to the west.
He was a descendant of Tipu Sultan, the famous 18th-century ruler of the kingdom of Mysore.
Noor was brought up in Paris and the family moved to London when Paris was occupied by the Germans in 1940 during the Second World War.
In London, Noor joined the Women's Auxiliary Air Force and was later recruited for the Special Operations Executive, a secret organisation started by Prime Minister Winston Churchill.
