Wilhelm Reich
I think that orgonite is pseudo-science, but it's a pretty interesting story: escape from the Nazis, altering the weather, a tiff with Einstein. Wilhelm Reich at Wikipedia, but especially the discussion about the article.
reading the discussion reminds me of a discussion Liz and I had last month. She teaches at NYU and students use Wikipedia as a source. I don't think thats ok (mostly because it is lazy and was never ok when I was writing papers), but we were talking about what could make it ok, like keeping a copy of the version of an article you reference, or using articles only as a starting point and working from the references. And most interesting was the idea of discovering different angles on a topic by reading the discussion about the article.
