Pierre Daniel Huet (French: [y.ɛ]; Latin: Huetius; 8 February 1630 – 26 January 1721) was a French churchman and scholar, editor of the Delphin Classics, founder of the Academie du Physique in Caen (1662-1672) and Bishop of Soissons from 1685 to 1689 and afterwards of Avranches.
He was born in Caen in 1630, and educated at the Jesuit school there. He also received lessons from a Protestant pastor, Samuel Bochart. By the age of twenty he was recognized as one of the most promising scholars of his time. In 1651 he went to Paris, where he formed a friendship with Gabriel Naudé, conservator of the Mazarin Library. In the following year Samuel Bochart, being invited by Queen Christina of Sweden to her court at , took his friend Huet with him. This journey, in which he saw Leiden, Amsterdam and Copenhagen, as well as Stockholm, resulted chiefly in the discovery, in the Swedish royal library, of some fragments of Origen's Commentary on St Matthew, which gave Huet the idea of editing and translating Origen into Latin, a task he completed in 1668. He eventually quarrelled with Bochart, who accused him of having suppressed a line in Origen in the Eucharistic controversy. While working on Origen's Greek text, Huet wrote a separate treatise on translation history, theory, and practice, the "De optimo genere interpretandi" ("On the best kind of translating") in two books (first published 1660; 3rd and last ed. Amsterdam, 1683).
