Four color theorem - Wikipedia, the free encyclopedia The conjecture was first proposed in 1852 when Francis Guthrie, while trying to color the map of counties of England, noticed that only four different colors were needed. (Guthrie graduated in 1850, and later became a professor of mathematics in South Africa). At the time, Guthrie was a student of Augustus De Morgan at University College. en.wikipedia.org /wiki/Francis_Guthrie

Biography of Lewis Van Gilder GUTHRIE, M. D. Francis Guthrie was a native of New York State, and for forty years was a minister of the Methodist Episcopal Church in West Virginia, where he died at the age of eighty-four. Judge Francis A. Guthrie left the college at Meadville, Pennsylvania, to enlist as a private in the Union army, September 10, 1861, in November, 1862, was promoted to first lieutenant and in March, 1863, to captain of Company E, One Hundred and Eleventh Pennsylvania Infantry. In and for this state hospital Doctor Guthrie has labored with unflagging zeal now for twenty years and, including his previous service at Spencer, he has been under seven different governors, a fact that to persons understanding the fluctuations of politics is peculiarly significant of Doctor Guthrie's splendid abilities and consecration to his task. www.electricscotland.com /history/world/bios/guthrie_lewis.htm

Historical perspective for Guthrie Guthrie Castle, on the Lunan's left bank, 1 mile NW of the junction, is a stately old pile, with massive walls 10 feet thick and 60 high, whose battlements out-top a mass of embosoming wood. Guthrie is in the presbytery of Arbroath and synod of Angus and Mearns; the living is worth £229. Repaired and enlarged in 1848 from designs by the late Mr David Bryce, it was founded in 1468 by Sir David Guthrie of Guthrie, comptroller of the exchequer, whose son, Sir Alexander, fell at Flodden (1513), and whose present descendant, John Douglas Maude Guthrie, Esq. www.geo.ed.ac.uk:81 /scotgaz/towns/townhistory4176.html

MyClan.com : Clan Guthrie : Clan History Sir David Guthrie of Guthrie was armour bearer to the king and captain of the guard, later being appointed Lord Treasurer of Scotland in 1461. The Guthries were quick to support the reformed religion, and in 1567 signed a bond upholding the authority of the infant King James VI against that of his mother, Queen Mary. John Douglas Guthrie of Guthrie served in the cavalry during the Egyptian campaign of 1882 and married Mary, daughter of Duncan Davidson of Tulloch. www.myclan.com /clans/Guthrie_45

chris Francis Guthrie was born on January 22, 1831 in London, England. Guthrie would be happy to know that a mere 124 years after he thought out the conjecture; an IBM 360 in Urbana, Illinois would prove it. The diversity of Guthrie’s knowledge was evident when he delivered a lecture titled, “The Heat of the Sun in South Africa.” He pointed out in his introduction that it must be probable for energy from the sun be able to be transformed into mechanical power. www.facstaff.bucknell.edu /udaepp/090/w3/chrisc.htm

Last doubts removed about the proof of the Four Color Theorem The story of the Four Color Problem begins in October 1852, when Francis Guthrie, a young mathematics graduate from University College London, was coloring in a map showing the counties of England. Guthrie's question became known as the Four Color Problem, and it grew to be the second most famous unsolved problem in mathematics after Fermat's last theorem. Indeed, the problem of coloring the map (in the sense of Guthrie's problem) can be reformulated in terms of coloring the network: color the nodes of the network in such a way that any two nodes which are connected together must have different colors. www.maa.org /devlin/devlin_01_05.html

The Four In 1852 Francis Guthrie was the first to propose that only four colors were needed. Francis Guthrie figured this out and tried to prove why it was. Guthrie was a part-time mathematician who, one day, while drawing a map of the counties of Britain noticed he needed only four colors to color the map with no county touching others with its same color. www.science.gmu.edu /~ssmith7/MapPage.htm

76 BOOK II Guthrie married June 15, 1889, Margaret Lynn English, who was born April 28, 1869, at Point Pleasant, W. Va. She is a daughter of John W. English, one time Judge of the Supreme Court of Appeals of W. Va., who was born Jan. 31, 1831; married Fannie Lewis, who was born Nov. 10, 1839. She is the cousin mentioned in the case of smallpox, under the care of Dr. Samuel Guthrie, when as a volunteer, Sarah was vaccinated by the doctor and slept in the room with the smallpox patient to demonstrate the efficacy of the doctor's serum. Sarah Guthrie volunteered to act as nurse and both she and the doctor passed successfully and triumphantly through the ordeal; and thenceforth his advance to distinction was rapid. www.brightok.net /~lguthrie/Booktwo.htm

He was a bright boy and made rapid progress in school. Guthrie, son of J. Alexander Guthrie and Kathleen Parsons, went into the service during the World War, at Warren, Ohio, May 26, 1918, and trained at Camp Gordon, Ga. His outfit was sent overseas, arriving in France Aug. 9, 1918. Jane Guthrie, fourth child and second daughter of Alexander Guthrie and Mary Maffett, "married Milton Fleming, with whom she raised a family of five or six children in Clarion Township where she died at an advanced age in 1875. www.brightok.net /~lguthrie/Page334-.htm

The four colour theorem Francis Guthrie showed his brother some results he had been trying to prove about the colouring of maps and asked Frederick to ask De Morgan about them. After graduating from London he studied law but by this time his brother Frederick Guthrie had become a student of De Morgan. Charles Peirce in the USA attempted to prove the Conjecture in the 1860's and he was to retain a lifelong interest in the problem. www-groups.dcs.st-and.ac.uk /~history/HistTopics/The_four_colour_theorem.html

4-colour theorem As Francis Guthrie long ago observed, every map with only a small number of countries can easily be colored with only four colors; the challenge is to prove that four colors suffice for every conceivable map. The question was first posed in 1852 by Francis Guthrie, a mathematics graduate student in London at the time. The proof that every planar map is four colorable was achieved in 1976 by Kenneth Appel and Wolfgang Haken, working together at the University of Illinois at Urbana-Champaign with the substantial help of a computer. mathcentral.uregina.ca /RR/database/RR.09.97/fisher1.html

ryanp.htm The concept of the Four Coloring Theorem was born in 1852 when Francis Guthrie noticed that he only needed four different colors to color in a map of England. Francis wondered if De Morgan would be able to tell him if it was true or not. Through his brother, Frederick, Francis communicated his discovery to De Morgan. www.facstaff.bucknell.edu /udaepp/090/w3/ryanp.htm

Murphy, who VMS born in 1880, at Monmouth, Ore., daughter of John L. Murphy, who was born in 184k at Monmouth, Ill.; married Ruth Rohrer, who was born in 1852. www.brightok.net /~lguthrie/Booktwoa.htm

Four-color map theorem Francis Guthrie, a 21-year-old mathematics student at University College in London, was mapping the counties of England in 1852 when he noticed that he only needed four colors for the map. He asked his younger brother, Frederick Guthrie, if this was true for any map. Anyone who can prove the theorem without the computer may win the Fields Medal, the math equivalent of the Nobel Peace Prize. math.youngzones.org /4color.html

Mudd Math Fun Facts: Four Color Theorem Francis Guthrie made this conjecture in 1852, but it remained unproven until 1976, when Wolfgang Haken and Kenneth Appel showed that it was true! It is easy to show that you need at least four colors, because Figure 1 shows a map with four countries, each of which is touching the other. Also, quite interestingly, this proof required the assistance of a computer to check 1,936 different cases that every other case can be reduced to! www.math.hmc.edu /funfacts/ffiles/10003.4.shtml

Fortis Benefits Unveils Fortis Advantage Online Services "These kinds of data changes can be made totally at the customer’s convenience and without communication delays," said Francis "Bud" Guthrie, Fortis Benefits’ executive vice president. Guthrie said bill reconciliation is simplified with the online service because census information can be updated in a timely manner, without gaps due to mail delays and other factors. "The invoice usually is more accurate because it is based on the most current employee data, not on information that is delayed in the mail," Guthrie said. www.fortisbenefits.com /company/press_re/faos.htm

The 4 Color Map Problem In 1852, Francis Guthrie wrote to his brother Frederick saying it seemed that four colors were always sufficient, did Frederick know a proof.
