Henry Stuart Jones (1867–1939) was Camden Professor of Ancient History at the University of Oxford. A distinguished ancient historian and lexicographer, he is remembered both for his OCT of Thucydides (1898–1902) and for his monumental revision of Liddell and Scott's Greek-English Lexicon (9th edition, 1925–1940), universally known as "LSJ" — the standard Greek dictionary still in daily scholarly use.

Jones's OCT of Thucydides (2 vols., 1898–1902, revised with apparatus by J. E. Powell, 1942) was the standard critical text for most of the 20th century. Based on careful collation of the principal manuscripts, particularly the Laurentian manuscript (Laur. 69.2, 10th century) and its relatives, Jones's text is conservative, trusting the best manuscript witnesses and marking clearly where he departs from them. The OCT series provides a clean text with a selective apparatus criticus — more concise than a full Teubner apparatus but recording all variants of scholarly significance.
