Here is the article on the inventor of top hats:
John Hetherington was an English haberdasher who supposedly modified the riding hat of the day into a Top Hat, widening the brim and lengthening it. In 1797, he caused a riot in the streets of London. People are said to have run in terror, dogs barking, women fainting. The crowd broke the arm of an errand boy as they ran past. Hetherington was charged in court with wearing “a tall structure having a shining luster calculated to frighten timid people”, and was fined Â£50.
