Staff Reviews

What an incredible, beautiful little volume for the entire history of seamanship. Unitl just 300 years ago, sailors were unable to measure longitude. Basically they were lost unless they could see land. John Harrison set out to  make a clock that would keep perfect time at sea, ignoring the fact that it hadn't yet been done with a clock on land. The result was unhindered global exploration.

— Andrew


Anyone alive in the eighteenth century would have known that "the longitude problem" was the thorniest scientific dilemma of the day-and had been for centuries. Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives and the increasing fortunes of nations hung on a resolution. One man, John Harrison, in complete opposition to the scientific community, dared to imagine a mechanical solution-a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is the dramatic human story of an epic scientific quest and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world.

Praise For…

Praise for Longitude:

“This is a gem of a book.”—Christopher Lehmann-Haupt, New York Times

“A simple tale, brilliantly told.”—Washington Post Book World

“As much a tale of intrigue as it is of science…A book full of gems for anyone interested in history, geography, astronomy, navigation, clockmaking, and—not the least—plain old human ambition and greed.” —Philadelphia Inquirer

“Only someone with Dava Sobel’s unusual background in both astronomy and psychology could have written it. Longitude is a wonderful story, wonderfully told.”—Diane Ackerman, author of A Natural History of the Senses

“The marine chronometer is a glorious and fascinating object, but it is not a simple one, and its explanation calls for a writer as skilled with words as the watchmakers were with their tools; happily such a writer has been found in Dava Sobel.”—Patrick O’Brian, author of The Commodore and the Aubrey/Maturin series
