**John Charles Fields**, FRS, FRSC (May 14, 1863 - August 9, 1932) was a Canadian mathematician and the founder of the Fields Medal for outstanding achievement in mathematics. Born in Hamilton, Ontario, Fields graduated from Hamilton Collegiate Institute in 1880 and the University of Toronto in 1884 before leaving for the United States to study at Johns Hopkins University in Baltimore, Maryland. Fields received his Ph.D. in 1887. His thesis, entitled *Symbolic Finite Solutions and Solutions by Definite Integrals of the Equation d ^{n}y/dx^{n} = x^{m}y*, was published in the

*American Journal of Mathematics*in 1886.

Fields taught for two years at Johns Hopkins before joining the faculty of Allegheny College in Meadville, Pennsylvania. Disillusioned with the state of mathematical research in North America at the time, he left for Europe in 1891, locating primarily in Berlin, Göttingen and Paris, where he associated with some of the greatest mathematical minds of the time, including Karl Weierstrass, Felix Klein, Ferdinand Georg Frobenius and Max Planck. Fields also began a friendship with Gösta Mittag-Leffler, which would endure their lifetimes. He began publishing papers on a new topic, algebraic functions, which would prove to be the most fruitful research field of his career.

Fields is best known for his development of the Fields Medal. Fields began planning the award in the late 1920s but, due to deteriorating health, never saw the implementation of the medal in his lifetime. He died on August 9, 1932 after a three-month illness; in his will, he left $47,000 for the Fields Medal fund.

Fields Medal is considered to be the Nobel Prize in Mathematics, although there are differences between the awards. First awarded in 1936, the medal was reintroduced in 1950 and has been awarded every four years since. It is awarded to two to four mathematicians, under the age of 40, who have made important contributions to the field.

Fields was elected fellow of the Royal Society of Canada in 1907 and fellow of the Royal Society of London in 1913.

The Fields Institute at the University of Toronto was named in his honour.

A book called "**Turbulent Times in Mathematics: The Life of J.C. Fields and the History of the Fields Medal"** by **Elaine McKinnon Riehm** and **Frances Hoffman,** provides useful information and sheds light on the happenings of the mathematical world during the times of J. C. Fields and his contributions.
