1956 - Christian missionaries killed by the Huaorani tribe - Operation Auca

Operation Auca
From Wikipedia, the free encyclopedia

Operation Auca was an attempt by five Evangelical Christian missionaries from the United States to make contact with the Huaorani people of the rainforest of Ecuador. The Huaorani, also known as the Aucas (the Quechua word for "naked savages"), were an isolated tribe known for their violence, against both their own people and outsiders who entered their territory. With the intention of being the first Protestants to evangelize the previously unreached Huaorani, the missionaries began making regular flights over Huaorani settlements in September 1955, dropping gifts. After several months of exchanging gifts, on January 2, 1956 the missionaries established a camp at "Palm Beach", a sandbar along the Curaray River, a few miles from Huaorani settlements. Their efforts came to an end on January 8, 1956, when all five—Jim Elliot, Nate Saint, Ed McCully, Peter Fleming, and Roger Youderian—were attacked and speared by a group of Huaorani warriors. The news of their deaths was broadcast around the world, and Life magazine covered the event with a photo essay.

The deaths of the men galvanized the missionary effort in the United States, sparking an outpouring of funding for evangelization efforts around the world. Their work is still frequently remembered in evangelical publications, and in 2006 was the subject of the film production End of the Spear. Several years after the death of the men, the widow of Jim Elliot, Elisabeth, and the sister of Nate Saint, Rachel, returned to Ecuador as missionaries with the Summer Institute of Linguistics (now SIL International) to live among the Huaorani. This eventually led to the conversion of many, including some of those involved in the killing. While largely eliminating tribal violence, their efforts exposed the tribe to exploitation and increased influence from the outside. This has caused Huaorani culture to begin to disappear, but anthropologists argue over the ultimate effect—some negatively view the missionary work as cultural imperialism, while others contend that the influence has been beneficial for the tribe.

Sam Gosling - Snoop: The Secret Language of Stuff

The Commonwealth Club of California
San Francisco, CA
Jun 16th, 2008

Does what's on your desk reveal what's on your mind? Do those pictures on your walls tell true tales about your character? Is your favorite outfit about to give you away?

For the last 10 years psychologist Gosling has been studying how people project (and protect) their inner selves. By exploring our private worlds (desks, bedrooms, even our clothes and cars), he shows not only how we showcase our personalities in unexpected ways, but also how we create personality in the first place, communicate it others and interpret the world around us - The Commonwealth Club of California
