Allan Lewis may refer to:
Allan Sydney Lewis (born December 12, 1941 in Colón, Panama) is a former professional baseball player. He was an outfielder and pinch runner over parts of 6 seasons (1967–1973) with the Kansas City/Oakland Athletics. Lewis was a member of the 1972 and 1973 World Series champion Athletics. For his career he batted .207 with 1 home run and 44 stolen bases in 156 games. Lewis is one of only seven players with more career game appearances than plate appearances.
He was dubbed "The Panamanian Express" for his base-stealing ability and his country of origin, in contrast to the train run called the Panama Limited.
As a minor leaguer with the Leesburg Athletics in 1966, Lewis set a minor league single-season record with 116 steals, which stood until 1980, when Alan Wiggins stole 120.
A lewis (sometimes called a lewisson) is one of a category of lifting devices used by stonemasons to lift large stones into place with a crane, chain block, or winch. It is inserted into a specially prepared hole, or seating, in the top of a stone, directly above its centre of mass. It works by applying principles of the lever and utilises the weight of the stone to act on the long lever-arms which in turn results in a very high reaction force and friction where the short lever-arms make contact with the stone inside the hole and thereby prevents slipping.
The name lewis may come from the Latin levo -avi, -atum meaning to levitate or lift, but the Oxford English Dictionary Online states, "the formation and the phonology are not easily explained on this hypothesis", preferring "origin obscure", and speculating that the term may derive from a personal name. The Romans used the lewis. The specially shaped hole that is shaped to fit the device is known as a lewis hole. Lewis holes in the uppermost masonry coursings are neatly repaired with matching indented plugs after the stone has been set in place.
Lewis (named after Meriwether Lewis) is an autonomous robot that performs the job of a wedding photographer: it attends social events, moves around, and takes digital photographs of people. It is a research project of the Media and Machines Laboratory at Washington University.
Lewis has been featured on slashdot, on CNN's website, and in various North American newspapers.
In 2002, Lewis received -- and declined -- an invitation to Nelly's 24th birthday party.
Lewis (first name and dates unknown) was an English cricketer who was associated with Middlesex and made his first-class debut in 1830.
