Sir Thomas Little HeathKCB KCVO FRS FBA (/hiːθ/; 5 October 1861 – 16 March 1940) was a British civil servant, mathematician,classical scholar, historian of ancientGreek mathematics, translator, andmountaineer. He was educated atClifton College.^[3] Heath translated works ofEuclid of Alexandria,Apollonius of Perga,Aristarchus of Samos, andArchimedes ofSyracuse into English.

Heath was born inBarnetby-le-Wold, Lincolnshire, England, being the third son of a farmer, Samuel Heath, and his wife Mary Little. He had two brothers and three sisters.^[4] He was educated atCaistor Grammar School andClifton College before enteringTrinity College, Cambridge, where he was awarded an ScD in 1896^[5] and became an Honorary Fellow in 1920.^[6] He got first class honours in both the classicaltripos and mathematicaltripos and was the twelfthwrangler in 1882. In 1884 he took the Civil Service examination and became an Assistant Secretary to the Treasury, finally becoming Joint Permanent Secretary to the Treasury andauditor of the Civil List in 1913. He held the position till 1919 when he was appointed as the comptroller of the National Debt Office, from which he retired at the end of 1926 because of age limitations. He was honoured for his work in the Civil Service by being appointedCompanion of theOrder of the Bath in 1903, Knight Commander of the Order of the Bath in 1909, andKnight Commander of theRoyal Victorian Order in 1916.^[7] He was elected aFellow of the Royal Society in 1912. He was a president of the Mathematical Association in 1922-23, and a fellow of the British Academy.^[4]

He had married professional musician Ada Mary Thomas in 1914;^[4] they had a son, Geoffrey Thomas Heath, and a daughter, Veronica Mary Heath. Heath's son Geoffrey went to Trinity College, Cambridge, before becoming a teacher atAmpleforth College, and had 6 children.

Heath died inAshtead, Surrey, on 16 March 1940.^[4]

Heath was distinguished for his work in ancient Greek mathematics and was the author of several books on ancient Greek mathematics. It is primarily through Heath's translations that modern English-speaking readers are aware of what Archimedes did. His translation of the celebratedArchimedes Palimpsest, however, was based on a transcription that hadlacunae, which scholars such asReviel Netz have been able to fill in to a certain extent, by exploiting scientific methods of imagery not available in Heath's time.

When Heath'sWorks of Archimedes was published in 1897, the Archimedes Palimpsest had not been extensively explored. Its significance was not recognised until 1906, when it was examined by Danish professorJohan Ludvig Heiberg. The palimpsest contained an extended version ofStomachion, and a treatise entitledThe Method of Mechanical Theorems that had previously been thought lost. These works have been a focus of research by later scholars.
