Context paragraphs:
World altitude record (mountaineering): In the history of mountaineering, the world altitude record referred to the highest point on the Earth's surface which had been reached, regardless of whether that point was an actual summit.  The world summit record referred to the highest mountain to have been successfully climbed.  The terms are most commonly used in relation to the history of mountaineering in the Himalaya and Karakoram ranges, though modern evidence suggests that it was not until the 20th century that mountaineers in the Himalaya exceeded the heights which had been reached in the Andes.  The altitude and summit records rose steadily during the early 20th century until 1953, when the ascent of Mount Everest made the concept obsolete.

Buckeye Lake (Ohio): Buckeye Lake is a reservoir in Fairfield, Licking, and Perry Counties in the U.S. state of Ohio.

With the demise of the canal system in the early 20th century, usage of the lake shifted to recreation.

Ashley, New Forest: Ashley is a village located in the southwest of Hampshire, England.  It lies on the eastern outskirts of New Milton in the New Forest district, and is two miles (3 km) inland from the sea.  Its history dates back to the Domesday book of 1086, when two estates were recorded.  In the 15th century much of Ashley merged with a neighbouring manor, and the estate became known as Ashley Arnewood.  As a village, Ashley began to develop in the 19th century when a church and a school were built.  Most of the current village was built in the 20th century, and today Ashley is effectively a suburb of New Milton.

Summit (game): Summit is a Cold War board wargame introduced in 1961 by Milton Bradley as "The Top Level Game of Global Strategy", with an updated release in 1971.

Strategy: Strategy (from Greek στρατηγία "stratēgia", "art of troop leader; office of general, command, generalship") is a high level plan to achieve one or more goals under conditions of uncertainty.  In the sense of the "art of the general", which included several subsets of skills including "tactics", siegecraft, logistics etc., the term came into use in the 6th century C.E. in East Roman terminology, and was translated into Western vernacular languages only in the 18th century.  From then until the 20th century, the word "strategy" came to denote "a comprehensive way to try to pursue political ends, including the threat or actual use of force, in a dialectic of wills" in a military conflict, in which both adversaries interact.

John Bradley &amp; Co: John Bradley & Co was a company established in 1800 by John Bradley at Stourbridge in the West Midlands area of England.  The company developed into a large industrial concern with furnaces, ironworks and mines.  Under James Foster, John Bradley's half brother, it was instrumental in bringing the first commercial steam locomotive into the Midlands area in 1829.  The firm stayed under family control until the early years of the 20th century when first the mining (1913) and then the ironworks (1919) were sold off.  Part of the business continued to trade under the name John Bradley & Co. (Stourbridge) Ltd until after the Second World War.

James Foster (ironmaster): James Foster (9 May 1786 – 12 April 1853) was a prominent Worcestershire ironmaster, coalmaster and senior partner in the important iron company of John Bradley & Co, Stourbridge, which was founded by his elder half-brother but greatly enlarged under his direction.  As well as the Stourbridge ironworks, the business owned a number of coal and ironstone mines, furnaces, forges and other works in the Black Country and near Ironbridge.  The business continued long after James Foster's death, ultimately being incorporated as John Bradley (Stourbridge) Ltd in the early 20th century.  In the late 19th century, the company was a member of the Marked Bar Association, whose members were the makers of the highest quality bar iron of the time.  Foster was also a partner in other companies including the engineering firm Foster, Rastrick and Company, which built the first steam locomotive to run on rails in the USA.  He was also a banker and landowner as well as being elected Member of Parliament and appointed as Improvement Commissioner for Stourbridge, and High Sheriff of Worcestershire.
