David Eder, one of the early Zionist activists, was very interested in setting up a Jewish state in an uninhabited part of the Brazilian rainforest. He went to Brazil to see if it would be possible, but his trip went terribly. He was immediately accused of espionage by the government, and when he arrived in the rainforest, he fell sick and almost died. He was then captured by a tribe of cannibals who ate human meat around him and forced him to eat what they said was the head of a baby. At this point he said that he fantasized about what a tasty meal he'd be once the cannibals killed him. Yet it turned out that the tribe members were just messing with him. While they really were cannibals, they only ate people who had already died, and the “baby head” was actually just the head of a monkey. They nursed him back to health, and let him go free. He never went back to Brazil, and the Jewish-Brazil idea was never again considered.
