Gottlieb Daimler  

"George Stephenson, a Scotchman, who had been building locomotives for the purpose of hauling coal from the mine-pit to smelting ovens and cotton factories, built his famous "travelling engine" which reduced the price of coal by almost seventy per cent and which made it possible to establish the first regular passenger service between Manchester and Liverpool, when people were whisked from city to city at the unheard-of speed of fifteen miles per hour. A dozen years later, this speed had been increased to twenty miles per hour. At the present time, any well-behaved flivver (the direct descendant of the puny little motor-driven machines of Daimler and Levassor of the eighties of the last century) can do better than these early "Puffing Billies."--The Story of Mankind (1921) by Hendrik van Loon
