In 1919, Prince Felix married his first cousin, Grand Duchess Charlotte of Luxembourg, and the couple had six children, including Grand Duke Jean. As Prince Consort, Prince Felix was president of the Luxembourg Red Cross between 1923 and 1932 and later between 1947 and 1969. He was also Colonel of the Luxembourg Volunteers Company and Inspector-General of the Luxembourg Army between 1945 and 1967. He was also deeply involved in the war effort during the Occupation and after the Liberation of Luxembourg during the Second World War. He continued to be a prominent figure until the Grand Duchess’ Abdication in 1964, and the couple continued to reside at the Château de Fischbach until his death on this day in 1970.
