Thomas Harriot
Encyclopedia
Thomas Harriot was an English
astronomer
, mathematician
, ethnographer, and translator. Some sources give his surname as Harriott or Hariot or Heriot. He is sometimes credited with the introduction of the potato
to Great Britain
and Ireland
. Harriot was the first person to make a drawing of the Moon
through a telescope, on July 26, 1609, over four months before Galileo
.
After graduating from Oxford University, Harriot travelled to the Americas
, accompanying the 1585 expedition to Roanoke
island funded by Raleigh
and led by Sir Ralph Lane
. Harriot was a vital member of the venture, having translated and learned the Carolina Algonquian language from two Native Americans, Wanchese and Manteo. On his return to England he worked for the 9th Earl of Northumberland
. At the Earl's house, he became a prolific mathematician and astronomer to whom the theory of refraction is attributed.

, Thomas Harriot attended St Mary Hall, Oxford
. His name appears in the school's registry dating from 1577.
as a mathematics tutor; he used his knowledge of astronomy/astrology
to provide navigational expertise, help design Raleigh's ships, and serve as his accountant. Prior to his expedition with Raleigh, Harriot wrote a treatise on navigation. In addition, he made efforts to communicate with Manteo
and Wanchese
, two Native Americans who had been brought to England. Harriot deciphered a phonetic alphabet
to transcribe their Carolina Algonquian language
.
Harriot and Manteo spent many days in one another's company; Harriot interrogated Manteo closely about life in the New World and learned much that was to the advantage of the English settlers. In addition, he recorded the sense of awe with which the Native Americans viewed European technology:
He made only one expedition, around 1585-86, and spent some time in the New World visiting Roanoke Island
off the coast of North Carolina
, expanding his knowledge by improving his understanding of the Carolina Algonquian language. As the only Englishman who had learned Algonkin prior to the voyage, Harriot was vital to the success of the expedition.
His account of the voyage was published in 1588 (probably written in 1587). The Report contains an early account of the Native American
population encountered by the expedition; it proved very influential upon later English explorers and colonists. He wrote: "Whereby it may be hoped, if means of good government be used, that they may in short time be brought to civility and the embracing of true religion." At the same time, his views of Native Americans' industry and capacity to learn were later largely ignored in favour of the parts of the "Report" about extractable minerals and resources.
As a scientific adviser during the voyage, Harriot was asked by Raleigh to find the most efficient way to stack cannon balls on the deck of the ship. His ensuing theory about the close-packing of spheres shows a striking resemblance to atomism
and modern atomic theory, which he was later accused of believing. His correspondence about optics with Johannes Kepler
, in which he described some of his ideas, later influenced Kepler's conjecture.
with whom he also resided at Syon House
, which was run by Henry Percy's cousin Thomas Percy
.
Harriot's sponsors began to fall from favour: Raleigh fell from favour, and Harriot's other patron Henry Percy
, the Ninth Earl of Northumberland, was imprisoned in 1605 in connection with the Gunpowder Plot
as he was the second cousin of one of the conspirators, Thomas Percy
.
Harriot himself was interrogated and briefly imprisoned but soon released. Walter Warner
, Robert Hues
, William Lower and other scientific peers were present around the Earl of Northumberland's mansion as they worked and lent a hand in the teaching of the family's children.
Halley's Comet in 1607 turned Harriot's attention towards astronomy. In early 1609 he bought a "Dutch trunke" (telescope), invented in 1608, and his observations were amongst the first uses of a telescope for astronomy. Harriot is now credited as the first astronomer to draw an astronomical object after viewing it through a telescope: he drew a map of the Moon
on July 26, 1609, preceding Galileo by several months. He also observed sunspot
s in December 1610.
, where he died. Sources cited below are among several that describe his condition as a cancer of the nose. In either case, Harriot apparently died from skin cancer
.
He died on 2 July 1621, three days after writing his will (discovered by Henry Stevens). His executors posthumously published his Artis Analyticae Praxis on algebra
in 1631; Nathaniel Torporley
was the intended executor of Harriot's wishes, but Walter Warner in the end pulled the book into shape. It may be a compendium of some of his works but does not represent all that he left unpublished (more than 400 sheets of annotated writing). It isn't directed in a way that follows the manuscripts and it fails to give the full significance of Harriot's writings.
and refraction
, and apparently discovered Snell's law
20 years before Snellius
did, although it was previously discovered by Ibn Sahl
; like so many of his works, this remained unpublished. In Virginia
he learned the local Algonquian
language, which may have had some effect on his mathematical thinking. He founded the "English school" of algebra
. He is also credited with discovering Girard's theorem, although the formula bears Girard's name as he was the first to publish it.
His only published work is his algebra book Artis Analyticae Praxis (1631) published posthumously in Latin. Unfortunately the editors did not understand much of his reasoning and removed the parts they did not comprehend such as the negative and complex roots of equations. Because of the dispersion of Harriot's writings the full annotated English translation of the Praxis was not completed until 2007.
The first biography of Harriot was written in 1876 by Henry Stevens of Vermont but not published until 1900 fourteen years after his death. The publication was limited to 167 copies and so the work was not widely known until 1972 when a reprint edition appeared. Interest in Harriot revived with the convening of a symposium at the University of Delaware in April, 1971 with the proceedings published by the Oxford University Press in 1974. John W. Shirley the editor (1908-1988) went on to publish A Sourcebook for the Study of Thomas Harriot (1981) and his Harriot biography (1983). The papers of John Shirley have been deposited in the University of Delaware Library.
Harriot's accomplishments remain relatively obscure because he did not publish any of his results and also because many of his manuscripts have been lost; those that survive are sheltered in the British Museum
and in the archives of the Percy family at Petworth House
(Sussex) and Alnwick Castle
(Northumberland).
An event was held at Syon House
, West London, to celebrate the 400th anniversary of Harriot's first observations of the moon on 26 July 2009. This event, Telescope400, included the unveiling of a plaque to commemorate Harriot by Lord Egremont. The plaque can now be seen by visitors to Syon House
, the location of Harriot's historic observations. His drawing made 400 years earlier is believed to be based on the first ever observations of the moon through a telescope. The event (sponsored by the Royal Astronomical Society
) was run as part of the International Year of Astronomy
(IYA).
The original documents showing Harriot's moon map of c. 1611, observations of Jupiter's satellites, and first observations of sunspots were on display at the Science Museum, London, from 23 July 2009 until the end of IYA.
The observatory
in the campus of the College of William and Mary
is named in Harriot's honour. A crater on the Moon
was belatedly named after him in 1970; it is on the Moon's far side and hence unobservable from Earth.
