Clipperton Island, Mexico

By 1910, nearly 100 people had begun to call Clipperton Island their home. One of those soldiers was a man named Ramon Arno with a checkered past. The only naturally occurring food on the island was a small supply of coconuts and whatever fish and birds they could hunt. But what those foods lacked was vitamin C, and so by late 1915, many on the island had scurvy.
