Toward the end of his life, he received recognition and a reward from Parliament. Harrison, who was the subject of Dava Sobell’s bestselling book Longitude(1995), which told the story of his solving of the problem of determining longitude at sea, had boasted that his latest. Harrison was a self-educated carpenter and clockmaker who achieved considerable fame in the mid-18th century for the marine chronometers that he designed to solve the problem that sailors then. Harrison gained support from the Longitude Board in building and testing his designs. John Harrison was a British clockmaker who invented the Chronometer in 1737, solving the problem of keeping track of different longitudes & time zones. In 1730, Harrison presented his first design, and worked over many years on improved designs, making several advances in time-keeping technology, finally turning to what were called sea watches. After closer examination, he suggests that it may be the work of John Harrison, the man who designed and built the worlds first successful maritime clock in the 18th century. The problem he solved was considered so important following the Scilly naval disaster of 1707that the British Parliament offered financial rewards of up to £20,000 (equivalent to £3.09 million in 2019) under the 1714 Longitude Act. The clock, made about 176870, also incorporates a system of gearing using Berthoud’s own variation on the kidney-shaped equation of time disk for indicating the annual irregularities of solar time, a device he published in 1763 in his Essai sur l’horlogerie. Harrisons solution revolutionised navigation and greatly increased the safety of long-distance sea travel. Harrison 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. ![]() He was well known for: Automata Clockmaking Biography As the son of a carpenter, Harrison’s initial material of choice was wood, and in fact, his first. He was born in West Yorkshire in the town of Foulby. John Harrison, Clockmaker A Brief Overview John Harrison’s invention of the marine chro nometer with which it became possible to deter mine a ship’s longitude while at sea with a de gree of certainty, revolutionised navigation. This meant that for the first time the crew could calculate their latitude. John Harrisons H1 clock Wikipedia Harrison, who had already gained a reputation for building fairly accurate clocks using nothing but wood, spent the next seven years building his H1. As a clockmaker, Harrison invented the Marine chronometer, which kept time at sea.
