Invention
The wheel clamp, originally known as the auto immobiliser, was invented in 1944 and patented in 1958 by Frank Marugg. Marugg was a pattern maker, a violinist with the Denver Symphony Orchestra, and a good friend to many Denver politicians and police department officials. The police department needed a solution to a growing parking enforcement problem. The city used to tow all ticketed cars to the pound, where they were often vandalised. Those who were ticketed sued the city for the damage and the police had to itemise everything in the cars. Dan Stills, a policeman, thought an immobiliser would avoid the expensive towing problem and approached Marugg with an idea on how to immobilise a vehicle.
The Denver police first used the wheel boot on 5 January 1955 and collected over US$18,000 (US$156,164 in 2012 dollars) in its first month of use. Although the wheel boot was first cast in steel, Marugg soon switched to a lighter aluminum-based alloy. Marugg later sold the device to parking lot owners, hotels and ski resorts, as well as a Jumbo version for farm equipment and larger vehicles. The Smithsonian Institution now has a copy of Marugg's boot on display in Washington, D.C.
The most infamous wheel clamp in the UK is the 'London Wheel Clamp'. The designer, Trevor Whitehouse and patent owner of device number GB2251416A filed the patent in 1991. He originally called the device the 'Preston' based on his home town in Lancashire. Primarily used on private land, its notoriety grew once it was introduced to public roads under the Road Traffic Regulations Act of 1991. (Commonly known as the de-criminalising of the yellow lines act.) The first areas in the country to be decriminalised were the 33 London Boroughs during 1993/94, hence the name change.

Famous quotes containing the word invention:
“The invention of photography provided a radically new picture-making process—a process based not on synthesis but on selection. The difference was a basic one. Paintings were made—constructed from a storehouse of traditional schemes and skills and attitudes—but photographs, as the man on the street put, were taken.”
—Jean Szarkowski (b. 1925)
“Correspondences are like smallclothes before the invention of suspenders; it is impossible to keep them up.”
—Sydney Smith (1771–1845)
“Justice is a moral virtue, merely because it has that tendency to the good of mankind, and indeed is nothing but an artificial invention to that purpose. The same may be said of allegiance, of the laws of nations, of modesty, and of good manners. All these are mere human contrivances for the interest of society.”
—David Hume (1711–1776)
