George was a lawyer, politician, cricketer, and an advocate of the Shakespeare authorship question. He chaired the first meeting of the Secular Education League, wrote a book on rationalism called "The Faith of an Agnostic" and was a well known animal welfare advocate. This "brief biography" includes a memory from his daughter, Elsie, that he died half way through writing a letter about animal welfare.
