Nicholas Saunderson

I came across this name in recent reading

Nicholas Saunderson LLD FRS (1682 – 1739) was a blind English scientist and mathematician. He may have been the earliest discoverer of Bayes theorem. He worked as Lucasian Professor, a post also held by Isaac Newton, Charles Babbage and Stephen Hawking.

Saunderson was born at Thurlstone, Yorkshire, in January 1682. When about a year old he lost his sight through smallpox; but this did not prevent him from acquiring a knowledge of Latin and Greek, and studying mathematics. As a child, he is also thought to have learnt to read by tracing the engravings on tombstones around St John the Baptist Church in Penistone with his fingers. His early education was at Penistone Grammar School, and he was introduced to Cambridge via meetings with the local gentry at Underbank Hall, near Penistone. In 1707, he arrived in Cambridge, staying with his friend Joshua Dunn, a fellow-commoner at Christ's College. During this time, he resided in Christ's but was not admitted to the University. With the permission of the Lucasian professor, William Whiston, Saunderson was allowed to teach, lecturing on mathematics, astronomy and optics. Whiston was expelled from his chair on 30 October 1710; at the appeal of the heads of colleges, Queen Anne awarded him an MA on 19 November 1711 so that he would be eligible to succeed Whiston as Lucasian professor. He was chosen as the fourth Lucasian professor the next day, defeating the Trinity College candidate Christopher Hussey, backed by Richard Bentley, when the electors split 6 to 4 in his favour. On 6 November 1718 Saunderson was elected a fellow of the Royal Society. He was resident at Christ's until 1723 when he married and took a house in Cambridge. He was created doctor of laws in 1728 by command of George II. He died of scurvy, on 19 April 1739 and was buried in the chancel of the parish church at Boxworth near Cambridge. He possessed the friendship of leading mathematicians of the time: Newton, Halley, etc. His senses of hearing and touch were acute, and he could carry out mentally long and intricate mathematical calculations. He devised a calculating machine or abacus, by which he could perform arithmetical and algebraic operations by the sense of touch; it was known as his "palpable arithmetic", and was described in his Elements of Algebra. Of his other writings, prepared for the use of his pupils, the only one which has been published is The Method of Fluxions. At the end of this treatise there is given, in Latin, an explanation of the principal propositions of Sir Isaac Newton's philosophy.
