Kempe studied at Trinity College, Cambridge where Arthur Cayley was one of his teachers. Trinity College is a constituent college of the University of Cambridge in Cambridge, England. Arthur Cayley ( August 16 1821 - January 26 1895) was a British Mathematician. He graduated with distinction in 1874. Despite his interest in mathematics he became a barrister, specializing in the ecclesiastical law. A barrister is a Lawyer found in many Common law Jurisdictions that employ a split profession (as opposed to a Fused profession) in relation Canon law is internal ecclesiastical law governing the Roman Catholic Church, the Eastern Orthodox churches and the Anglican Communion of churches He was knighted in 1913, the same year he become the Chancellor for the Diocese of London. See also Chancellor (disambiguation Two quite distinct officials of some Christian Churches have the title Chancellor. The Diocese of London forms part of the Province of Canterbury in England. He received the honorary degree D.C.L. from the University of Durham. Doctor of Canon Law ( Latin: Juris Canonici Doctor; JCD) is the Doctoral -level Terminal degree in the studies of Durham University is a University in Durham, England. It was founded as the University of Durham (which remains its official and legal name

In 1877 Kempe rediscovered a straight line linkage and published his influential lectures on the subject. The Peaucellier-Lipkin linkage (or Peaucellier-Lipkin cell) invented in 1864 was the first linkage capable of transforming rotary motion into perfect straight-line In 1879 he wrote his famous "proof" of the four color theorem, shown incorrect by Percy Heawood in 1890. The four color theorem (also known as the four color map theorem) states that given any plane separated into regions such as a political map of the states of a country Percy John Heawood ( 8 September, 1861 Newport Shropshire, England - 24 January, 1955 Durham, England Much later, his work lead to fundamental concepts such as the Kempe chain and unavoidable sets. In Mathematics, a Kempe chain is a device used mainly in the study of the Four colour theorem.

Kempe (1886) revealed a rather marked philosophical bent, and much influenced Charles Peirce. Charles Sanders Peirce (pronounced purse) (September 10 1839 &ndash April 19 1914 was an American Logician mathematician, philosopher Kempe also discovered what are now called multisets, although this fact was not noted until long after his death. In Mathematics, a multiset (or bag) is a generalization of a set.

Kempe was elected a fellow of the Royal Society in 1881. The Royal Society of London for the Improvement of Natural Knowledge, known simply as The Royal Society, is a Learned society for science that was founded in 1660 The Royal Society of London for the Improvement of Natural Knowledge, known simply as The Royal Society, is a Learned society for science that was founded in 1660 He was a president of the London Mathematical Society from 1892 to 1894. The London Mathematical Society ( LMS) is the leading mathematical society in England. He was also a mountain climber, mostly in Switzerland. “Alpinist” redirects here See also Alpinist (magazine Mountaineering is the Sport, Hobby or Profession of Switzerland (English pronunciation; Schweiz Swiss German: Schwyz or Schwiiz Suisse Svizzera Svizra officially the Swiss Confederation
