Walter Aiken Lewis (July 17, 1885 – May 29, 1956) was a Canadian rower who competed in the 1908 Summer Olympics.

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 (first name and dates unknown) was an English cricketer who was associated with Middlesex and made his first-class debut in 1830.
Lewis is a crater on the far side of the Moon. It lies along the western edge of the Montes Cordillera mountains that surround the Mare Orientale impact basin. This crater has been heavily disrupted by the formation of the basin, and it is covered by ejecta from the impact leaving only an uneven depression in the surface. The outer rim is roughly circular, and the interior is uneven.
