Jørgen Kieler was a Danish physician, remembered primarily for his participation in resistance activities under the German occupation of Denmark in the early 1940s. He was captured and was placed in a prison and Nazi concentration camps. Saved by the White Buses of the Bernadotte rescue, Kieler was treated for tuberculosis for two years after his release.
After the war, he wrote a book about his war-time experiences and supported other Danish concentration camp survivors as president of the Freedom Foundation of Denmark. He was director of the Danish Cancer Society.
