Longitude was dramatised for television by Charles Sturridge and Granada Film in 1999, and was shown in the United States by A & E.

This was not the transatlantic voyage demanded by the Board of Longitude, but the Board was impressed enough to grant Harrison £ 500 for further development.

Longitude was beyond Pytheas and his peers, but it was not of as great a consequence, because ships seldom strayed out of sight of land.

In 1999 he cofounded and was CEO of Longitude Systems.

* 1761: The problem of Longitude was finally resolved by the fourth chronometer of John Harrison

The results of the voyage were made public at a meeting of the Board of Longitude in early 1765, where it was disclosed that Harrison's chronometer had produced Bridgetown's longitude with an error of less than ten miles after a sea voyage of more than 5, 000 miles.

The position automatically made him an ex-officio member of the Board of Longitude and it was not long before a negative report was made on Harrison's chronometer, Maskelyne refusing to allow for the known rate at which Harrison's chronometer gained or lost time and thus dismissing it as inaccurate.

He was not alone in his position on lunar distances ; other members of the Board of Longitude and the Royal Society were also strongly biased toward lunars, as they saw the scientific solution being conceptually and intellectually superior to the mechanic's solution.

When eventually Harrison was paid the money owing to him, it was by a special Act of Parliament rather than the Board of Longitude.

In 1897, the Commission de décimalisation du temps was created by the French Bureau of Longitude, with the mathematician Henri Poincaré as secretary.

The Longitude Prize was a reward offered by the British government for a simple and practical method for the precise determination of a ship's longitude.

The prize, established through an Act of Parliament ( the Longitude Act ) in 1714, was administered by the Board of Longitude.

In 1816 he was secretary of a commission charged with ascertaining the precise length of the second's or seconds pendulum ( the length of a pendulum whose period is exactly 2 seconds ), and in 1818 he became secretary to the Board of Longitude and superintendent of the HM Nautical Almanac Office.

The Board of Longitude was the popular name for the Commissioners for the Discovery of the Longitude at Sea.

The establishment of the Board of Longitude was motivated by this problem and by the 1707 grounding of four ships of Vice-Admiral Sir Cloudesley Shovell's fleet off the Isles of Scilly, resulting in heavy loss of life.

With the significant problems considered as solved, the Board of Longitude was abolished by Act of Parliament in 1828.

On the abolition of the Board of Longitude in 1828, it was arranged that three scientific advisers to the Admiralty should be nominated from the council of the Royal Society.

* John Harrison's " H4 " wins him the Longitude prize for the Marine chronometer.

Despite a possible conflict of interests, Maskelyne being an advocate of the lunar distance method of determining longitude, the Board of Longitude sent him to Barbados in 1763 to calculate the longitude of the capital, Bridgetown by observation of Jupiter's satellites, and also to test his lunar distance method and compare its accuracy to John Harrison's chronometer, the No. 4 timekeeper.

The Centennial Challenges are based on a long history of technology prize contests, including the Longitude prize ( won by John Harrison ), the Orteig Prize ( won by Charles Lindbergh ), the Ansari X PRIZE ( won by Scaled Composites ), and the DARPA Grand Challenge ( won by Stanford University in 2005 and Carnegie Mellon University in 2007 ).

In 2001 he wrote and directed Longitude, based on Dava Sobell's best selling life of the clockmaker John Harrison which won the BANFF TV Festival Best Series award, two PAWS awards and five BAFTA ’ s.

In 1805, Earnshaw and Arnold were granted awards by the Board of Longitude for their improvements to chronometers ; Earnshaw received £ 2500 and John Arnold's son John Roger Arnold received £ 1672.

Eventually, after much argument, Earnshaw and Arnold were later granted awards by the Board of Longitude for their improvements to chronometers ; Earnshaw received £ 2500 and John Arnold's son John Roger Arnold received £ 1672.

Returning to England in 1762, he joined the Board of Longitude — a team of scientists who tested John Harrison ’ s marine chronometer on a voyage to Jamaica.

In 1730 Harrison created a description and drawings for a proposed marine clock to compete for the Longitude Prize and went to London seeking financial assistance.

While this scheme worked well enough to allow Harrison to meet the standards set by the Longitude Act, it was not widely adopted.

He demonstrated it to members of the Royal Society who spoke on his behalf to the Board of Longitude.

Established by the Longitude Act 1714, the Board gathered the greatest scientific minds of the day to work on the problem, including Sir Isaac Newton, and put up prizes for those who could demonstrate a working device or method.

* July-The Parliament of Great Britain offers the Longitude prize to anyone who can solve the problem of accurately determining a ship's longitude.

Around 1796 Earnshaw, who had temporarily lost interest in the Board of Longitude reward, was tempted back by the failure of Josiah Emery to win it.
