The Museum Henry Dunant is the only museum in the world that focuses on the life and work of the visionary initiator of the International Red Cross and the Geneva Conventions. Henry Dunant (1828-1910) spent the last 18 years of his life in Heiden. The Appenzell village with its classicist architecture was an internationally renowned health resort at the time. He wrote his memoirs here. At 800 m. above sea level, with a view of Lake Constance and across borders, he further developed his ideas for a more peaceful world and an International Court of Justice. It was in Heiden in 1901 that he received the announcement that he would be the first person to be awarded the Nobel Peace Prize. The museum dedicated to him is housed in the building where Dunant lived as a reclusive pensioner until his death on 30 October 1910.
