Dava Sobel

The work was inspired by Dava Sobel’s brief but fascinating book Longitude which tells the absorbing story of the eighteenth-century clockmaker John Harrison and John Harrison's mission to build an accurate chronometer for use at sea.

Sobel

Sobel’s first book “Longitude” chronicled the work of 18th century clockmaker John Harrison, who first devised a method for determining ships’ longitudes at sea, a perennial humdinger that had plagued the likes of Galileo and Isaac Newton.

by the Greek Eratosthenes

The longitude was developed by the Greek Eratosthenes (c. 276 BC – c. 195 BC) in Alexandria and Hipparchus (c. 190 BC – c. 120 BC) in Rhodes.

with Eratosthenes of Cyrene who lived between 276 and 194 before the Common Era (BCE)

The story of longitude, by many accounts, begins with Eratosthenes of Cyrene who lived between 276 and 194 before the Common Era (BCE).

John Harrison

Longitude is the dramatic human tale of an epic medical quest and of Harrison's forty-year obsession with development John Harrison's ideal timekeeper, identified at the present time because the chronometer.

the Greek, Eratosthenes who lived between 276 BC and 195BC

The concept of "longitude" was developed by the Greek, Eratosthenes who lived between 276 BC and 195BC.

Ptolemy

Ptolemy introduced longitude and latitude as well as aligning terrestrial and celestial observations.

Jerome Sturridge

In 2001 Jerome Sturridge 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 BAFTAs.

Claudius Ptolemy

Claudius Ptolemy introduced the concept of longitude and latitude lines, allowing for precise location plotting.

Eratosthenes, Anaximander, and Hipparchus

Eratosthenes, Anaximander, and Hipparchus are credited with developing the concept of longitude and latitude, and Eratosthenes seems to have developed the equirectangular map projection around 200 BC.

Arnold Wesker

One of Arnold Wesker's later works was Longitude, which explored the trials of John Harrison, a stubborn, self-educated genius from rural 18th century Lincolnshire who devised a clock which could tell the time, and hence one’s position, accurately on the roughest seas.

Written by Tim Wright, one of the creatives behind the RSC’s 2010 digital experiment, Such Tweet Sorrow, Longitude uses Google Hangouts (as did Midsummer Night’s Dreaming) to broadcast three 20-minute episodes of a new play about global climate change and water shortage.

Richard Rhodes

If anything, Richard Rhodes's Longitude is an apéritif which wets the appetite for other, more technical books on timekeeping.

by Erasthones

The concept of longitude was first unveiled by Erasthones in the 3rd Century BC, but until 1761, you could not tell longitude at sea, on long voyages.

Rembrandtszoon

Next, our copy is excluded also: the mere fact that Rembrandtszoon has recorded the longitude on May 18, 1643, which our copy fails to do at the said date, would make us doubt the possibility of our mathematician having made use of the latter, at least to the exclusion of other copies.

Hipparchus

Hipparchus is credited with developing the first regular global system of latitude and longitude around 150 BC.
