Mathematics professorship in the University of Cambridge, England
The Lucasian Chair of Mathematics () is a mathematics professorship in the University of Cambridge, England; its holder is known as the Lucasian Professor. The post was founded in 1663 by Henry Lucas, who was Cambridge University's Member of Parliament in 1639–1640, and it was officially established by King Charles II on 18 January 1664. It has been called the most celebrated professorship in the world, and the most famous academic chair in the world due to the prestige of many of its holders, and the groundbreaking work done by them. It was said by "The Daily Telegraph" to be one of the most prestigious academic posts in the world. Since its establishment, the professorship has been held by, among others, Isaac Newton, Charles Babbage, George Stokes, Joseph Larmor, Paul Dirac, and Stephen Hawking.
History.
Henry Lucas, in his will, bequeathed his library of 4,000 volumes to the university and left instructions for the purchase of land whose yielding should provide £100 a year for the founding of a professorship.
It is the third oldest chair of mathematics in Great Britain, after the Gresham Professor of Geometry at Gresham College and the Savilian Professor of Geometry at the University of Oxford. 
In the 1800s and following decades, the Lucasian professors "played important roles in making Britain the preeminent scientific state and in changing the university from a ‘gentleman’s club’ to a research institution."
Babbage applied for the vacancy in 1826, after Turton, but Airy was appointed. William Whewell (who considered applying, but preferred both Herschel and Babbage to himself) remarked that he would be the best professor, but that the heads of the colleges would not see that. Nonetheless, Babbage was appointed when the chair became free again two years later.
The current (19th) Lucasian Professor is Michael Cates, starting from 1 July 2015.
The previous holder of the post was theoretical physicist Michael Green who was a fellow in Clare Hall. He was appointed in October 2009, succeeding Stephen Hawking, who himself retired in September 2009, in the year of his 67th birthday, as required by the university. Green holds the position of Emeritus Lucasian Professor of Mathematics.
