A key quote: "In 1966, a report called Accidental Death and Disability: The Neglected Disease of Modern Society—commonly known as The White Paper—was

This eventually led to equipping ambulances with life saving equipment and trained paramedics. This started in the US in the late 60s and early 70s, and has spread to the rest of the world.
