I started very recently to study anthropology, only this year , so I didn't know any important antropologist until the last week when a classmate told me about Pierre Clastres and then a teacher spoke about him in a class. He is a french antropologist and ethnographer ( although he studied philosophy ), who was interested about american antropology, under the influece of another famous antropologist, Levi Strauss.  He worked with comunities from Paraguay and Brasil, specially with guaranies  and he has a very important participation on the "French may".  His most famous publication is "The society against the government", in general he talk about the normal authonomy of the human be, so he thought, against the evolutionism, that the government is not the natural way that a population organized, or not necessarily. I found interesting his thought because he talk about the leaders of primitives societies that have prestiges, but they can't become this to power separated of the society because they have a debt with his people. I like very much this idea because is very different of the way that we live today, we live in a society that many time it seems that the people have a debt with their leaders, while it must be the opposite.
