Sir Thomas Little Heath (5 October 1861 – 16 March 1940) was a British civil servant, mathematician, classical scholar, historian of ancient Greek mathematics, translator, and mountaineer. He was educated at Clifton College. Heath translated works of Euclid of Alexandria, Apollonius of Perga, Aristarchus of Samos, and Archimedes of Syracuse into English.

He was born in Barnetby-le-Wold, Lincolnshire, England and was awarded a DSc by Cambridge University. He was a Fellow of Trinity College, Cambridge and Assistant Secretary to the Treasury. He was distinguished for his work in Greek Mathematics and author several books on Greek mathematicians.

It is primarily through Heath's translations that modern English-speaking readers are aware of what Archimedes did. His translation of the celebrated Archimedes Palimpsest, however, was based on a transcription that had lacunae, which scholars such as Reviel Netz have been able to fill in to a certain extent, by exploiting modern scientific methods of imagery not available in Heath's time.

When Heath's Works of Archimedes was published in 1897, the Archimedes Palimpsest had not been extensively explored. Its significance was not recognized until 1906, when it was examined by the Danish professor Johan Ludvig Heiberg. The palimpsest contained an extended version of Stomachion, and a treatise entitled The Method of Mechanical Theorems that had previously been thought lost. These works have therefore been the focus of research by modern scholars.

He was elected a Fellow of the Royal Society in May 1912. ^[1]
