Isaac Newton is one of the most famous scientists of all time, and His book Philosophiae Naturalis Principia Mathematica is arguably the most important book published in the history of science. He was a fascinating and enigmatic character. He suffered several major nervous breakdowns over the course of his life, and he spent many years researching alchemy (this investigation into the hidden forces of nature helped to lead him to his discovery of the action-at-a-distance nature of the law of gravity). You can read more about Newton here. He would make a great "excellent example" for your essay.
