Harold Jeffreys was a British mathematician, geophysicist, astronomer, and philosopher and was one of the great original applied-mathematical thinkers of the 20th Century. He has made many contributions in a wide range of fields. Jeffreys also wrote a very prominent book in the Probability world that is still used today called "Theory Of Probability". This book was an attempt to develop a fundamental theory on scientific inference based on Bayesian statistics. Harold Jeffreys was an important influence on many fields of science and mathematics during his life and many of his theories still have relevance today. Harold Jeffreys was born on April 22, 1891 in Fatfield, England. Jeffreys attended school at Fatfield until, in 1903, he was awarded a scholarship to attend Rutherford College, in Newcastle, England. Then in 1907 Jeffreys went to Armstrong College, in Newcastle, which later became Newcastle University (Sir Harold Jeffreys | Biography). There he studied mathematics, physics, chemistry, and geology, and graduated in 1910 with distinction in mathematics. He then went to St. John's College, Cambridge after Newcastle, having gotten one of four mathematic scholarships. He became a fellow of St. John's College, Cambridge and remained a fellow for the rest of his life. After a little time away Jeffreys returned to the University of Cambridge in 1922…show more content…
One of his most significant contributions to statistics was his use of applying his version of the Bayesian argument to statistics. Jeffreys referred to the Bayesian approach to Probability & Statistics as Inverse Probability (Sir Harold Jeffreys | Biography). Even though early writers used the Bayesian methods, Jeffreys has a good claim to be considered the first Bayesian statistician because he only used Bayesian methods in his work (Harold Jeffreys as a
