Newton Papers
Plato is my friend, Aristotle is my friend, but my greatest friend is truth." —Sir Isaac Newton
(MS Add.3996, 88r)
Cambridge University Library holds the largest and most important collection of the scientific works of Isaac Newton (1642-1727). We present here an initial selection of Newton's manuscripts, concentrating on his mathematical work in the 1660s. Over the next few months we will be adding further works until the majority of our Newton Papers are available on this site.
Newton was closely associated with Cambridge. He came to the University as a student in 1661, graduating in 1665, and from 1669 to 1701 he held the Lucasian Chair of Mathematics. Under the regulations for this Chair, Newton was required to deposit copies of his lectures in the University Library. These, and some correspondence relating to the University, were assigned the classmarks Dd.4.18, Dd.9.46, Dd.9.67, Dd.9.68, and Mm.6.50.
In 1699 Newton was appointed Master of the Mint, and in 1703 he was elected President of the Royal Society, a post he occupied until his death.
After his death, the manuscripts in Newton's possession passed to his niece Catherine and her husband John Conduitt. In 1740 the Conduitt's daughter, also Catherine, married John Wallop, who became Viscount Lymington when his father was created first Earl of Portsmouth. Their son became the second earl and the manuscripts were passed down succeeding generations of the family.
In 1872 the fifth earl passed all the Newton manuscripts he had to the University of Cambridge, where they were assessed and a detailed catalogue made. Based on this catalogue, the earl generously presented all the mathematical and scientific manuscripts to the University, and it is these that form the Library's 'Portsmouth collection' (MSS Add. 3958-Add. 4007).
The remainder of the Newton papers, many concerned with alchemy, theology and chronology, were returned to Lord Portsmouth. They were sold at auction at Sotheby's in London in 1936 and purchased by other libraries and individuals.
In 2000 Cambridge University Library acquired a very important collection of scientific manuscripts from the Earl of Macclesfield, which included a significant number of Isaac Newton's letters and other papers.
