Walter Lewin was a professor at MIT for 49 years. He became quite prestigious, not just on campus but online as well with his online video courses. In 2013 he began to create online versions of his classes for people to take as well. And in October 2014 it brought him sexual harassment charges. Immediately after said charges were brought, Lewin was fired and his videos were taken down from the internet. I donâ€™t believe that his videos should have been taken down off the internet.
