Inventions that changed the world Episode 2: The Gun Shown on 7th & 8th August The gun has generally had a negative press. The need for a more accurate cannon led James Wilkinson, in 1774, to invent a tube boring machine. This was then used by James Watt to make more efficient steam engines, which in turn powered the industrial revolution. Gun maker Sam Colt was not only the inventor of the first reliable revolver, which helped early settlers to defeat the Indians and led to the myth of the cowboy, but also invented a new method of manufacturing guns the production line. Henry Ford made his Model T car affordable by copying 'the Colt method'. Even the car exhaust pipe was a spin-off of the gun silencer. Street lighting was introduced to deter armed highway robbers whilst trauma medicine and the control of infections were initially developed to deal with gun injuries. In the course of showing how the gun developed from a simple tube to a device capable of firing a million rounds a minute, Jeremy builds his own gun, goes FISHing (Fighting In Someone else's House) with British soldiers, and tests the limits of the bullet proof vest.
