Joseph Wimble was the only son of an analytical chemist, who, having made considerable profits out of an Invisible Sticking Plaster, sent the boy to Charterhouse and Cambridge in the hope that he would turn out a gentleman. When Joseph left Cambridge his father left business, referred to himself as Expert, used a couple of letters after his name, and suggested making the Grand Tour of Europe together as a finishing touch.
