Dokument 1 – John Harrison

Převzato z https://en.wikipedia.org/wiki/John_Harrison

John Harrison (1693–1776) was a self-educated English carpenter and clockmaker who invented the marine chronometer, a long-sought-after device for solving the problem of calculating longitude while at sea.

Harrison's solution revolutionized navigation and greatly increased the safety of long-distance sea travel. The problem he solved was considered so important following the Scilly naval disaster of 1707 that the British Parliament offered financial rewards of up to £20,000 (equivalent to £3.22 million in 2022) under the 1714 Longitude Act.
