Land, Edwin Herbert, 1909-91, American inventor and photographic pioneer. While at Harvard, Land became interested in the properties and manipulation of polarized light. He left Harvard and, in 1932, created Polaroid J Sheet, a polarizing material that was inexpensive and easy to fabricate. In partnership with George Wheelwright, a Harvard physics instructor, Land in 1937 founded the Polaroid Corporation, where he adapted polarized materials for sunglasses, 3-D movies, and military use. In 1947 he demonstrated a single-step photographic process that enabled pictures to be developed in 60 seconds; a color process was marketed in 1963, and a self-developing positive print followed in 1973. In the original Land process, a negative material was exposed inside the camera and then drawn out, while being squeezed against a layer of reagent and a positive material. After 60 (later 10) seconds the layers could be separated and the negative discarded. In the current Polacolor process, light makes a series of latent images on appropriate dye layers of the film sheet; when the picture is ejected from the camera, processing reagent activates the image in these lower layers, which reaches final form after several minutes. The resulting print is protected by a hard plastic film. (See photographic processing.) Holder of more than 500 patents, Land founded the Rowland Institute of Science in 1960 and devoted his time to it after his retirement from Polaroid in 1980.

land, in law, any ground, soil, or earth regarded as the subject of ownership, including trees, water, buildings added by humans, the air above, and the earth below. Private ownership of land does not exist in groups that live by hunting, fishing, or herding; e.g., in pre-Columbian times in America, the tribe owned the land, and each individual had equal access to it and equal rights to its use. In simple agricultural groups, as in early Europe, the village community made an annual allotment of land to individuals for cultivation. Similar allotments were made under the manorial system. A communal form of rural landholding persisted in Russia into the 20th cent. and still exists in India. The modern sovereign state asserts dominion over all property within its territorial limits, including the land, and by the right of eminent domain (see public ownership) can seize privately owned land for public use, with the proviso that the owner be justly compensated. In the former Soviet Union ownership of all land was vested in the nation outright, individuals and organizations being granted provisional rights to its use. Widely distributed private ownership of farmland has been regarded in Western countries as socially—if not always economically—advantageous. The concentration of landholding in a few hands has frequently led to political unrest and social upheaval, as in Latin America, Spain, Italy, the Middle East, and parts of Asia. In economics the term land is used to designate one of the main factors of production; it is another name for nature or natural resources. But few natural resources are free; farmland, for instance, is almost valueless without cultivation. In order to extract crops, minerals, and energy from the land, labor and capital must be applied. In economic theories of value, the share assigned to land as a factor in production is called rent.

Land's End (Cornish name: Penn an Wlas) is a headland on the Penwith peninsula, located near Penzance in Cornwall, England, United Kingdom. It is the most westerly tip of the southern mainland (for Great Britain as a whole it is Corrachadh Mòr, Ardnamurchan, Scotland which is 22 miles further west). It is often thought to be the most southerly point in the British mainland, but that honour in fact falls to Lizard Point, a few miles to the south-east. Visible from Land's End is the Longships Lighthouse. The Longships, a few miles out, is a serpentine and quartz island. Offshore, midway between Land's End and the Isles of Scilly, is the supposed location of the mythical lost land of Lyonesse, referred to in Arthurian literature.

The name has a particular resonance because it is so often used in outlining the length of Britain when races, walks and charitable events take place between Land's End and the Scottish village John o' Groats (the most north-easterly settlement in mainland Britain). The phrase Land's End to John o' Groats is used both as a literal journey and as a metaphor for great or all-encompassing distance, similar to the American phrase coast to coast.

In 1769 The Antiquarian, William Borlase wrote that,

"Of this time we are to understand what Edward I. says (Sheringham. p. 129.) that Britain, Wales, and Cornwall, were the portion of Belinus, elder son of Dunwallo, and that that part of the Island, afterwards called England, was divided in three shares, viz. Britain, which reached from the Tweed, Westward, as far as the river Ex; Wales inclosed by the rivers Severn, and Dee; and Cornwall from the river Ex to the Land's-End".

In 1987 Peter de Savary purchased Land’s End. He had two new buildings erected and much of the present theme park development was instigated by him. He sold both Land's End and John o' Groats for an undisclosed sum to businessman Graham Ferguson Lacey in 1991.

The current owners purchased Land’s End in 1996 and formed a company named Heritage Attractions Limited.
