3 Michael Faraday : Faraday is unique among the world’s greatest scientists, because he mainly taught himself. When he was 14 he became the apprentice of a book binder. While binding books, he would spend his spare time reading on a variety of different topics. After going to four lectures given by a scientist called Humphry Davy, he decided to work for him. Although he was denied a position at first he eventually became a lab assistant at the Royal Institution. Faraday went on to discover electromagnetic inductions and rotations, dia-magnetisation, the magneto-optical effect, and field theory.
