Here is a nice little article on Pierre Curie, the co-discoverer of radioactivity.
http://en.wikipedia.org/wiki/Pierre_Curie
There is a short summary of his education, discoveries and career. Basically, a nice stub article but by no means a full article.
And then it launches into a hugely detailed description of his experiences with a medium. Quite bizarre. And the experiences he describes are such basic magic tricks it really is quite illuminating about the man and/or his times i.e what people were willing to believe then because "science" had yet to catch-up.
I wonder how a one-line edit to the article saying "This shows that he had a good sense of humour" would be taken? :-)
