Edeltraud Fulda was a young Austrian dancer who developed Addison's disease (adrenal insufficiency) in the 1930s. By the mid-1940s — Europe ravaged, cortisone (which had only just been synthesised by Edward Kendall at Mayo Clinic in 1948) not yet available outside the United States — she was bedridden, near death, the brown pigmentation of late-stage Addison's covering her skin.
On pilgrimage to Lourdes in August 1948 she bathed in the spring waters. The cure was instantaneous and complete. She returned to Vienna and danced again. The Lourdes Medical Bureau and the International Medical Committee of Lourdes examined her repeatedly over the following seven years; on May 17, 1955 the Archbishop of Vienna formally recognised the cure as miraculous — the 53rd formally recognised Lourdes cure.
