Sir Thomas Little Heath KCB KCVO FRS FBA (/hiːθ/; 5 October 1861 – 16 March 1940) was a British civil servant, mathematician, classical scholar, historian of ancient Greek mathematics, translator, and mountaineer.

[3] Heath translated works of Euclid of Alexandria, Apollonius of Perga, Aristarchus of Samos, and Archimedes of Syracuse into English.

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.

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 scientific methods of imagery not available in Heath's time.

The palimpsest contained an extended version of Stomachion, and a treatise entitled The Method of Mechanical Theorems that had previously been thought lost.
