**Louis-Isaac Lemaistre de Sacy (March 29, 1613 – January 4, 1684), a priest of Port-Royal, was a theologian and French humanist. He is best known for his translation of the Bible, the most widely distributed French Bible in the 18th century, also known as the Bible de Port-Royal.
Louis-Isaac Lemaistre de Sacy was born in Paris, one of five sons of the Huguenot Isaac Le Maistre, and of Catherine Arnauld, who was one of the sisters of Marie Angélique Arnauld. In 1638, when his older brothers Antoine and Simon gave up their careers to retire to Port-Royal, Louis-Isaac joined them to see to his education.
In 1650 he published a collection of prayers, the Heures de Port-Royal, in which he translated the highly successful liturgical hymns.
De Sacy was imprisoned in the Bastille on May 13, 1666, and remained there until November 14, 1668. He took advantage of this time to complete the translation of the Old Testament into French from the Vulgate begun by his brother Antoine, and was thus the driving force behind a French-language translation of the Bible, called the Bible du Port-Royal or Bible de Sacy. After his release, Louis-Isaac spent much of his time revising his translation and drafting the commentaries he intended to add to each of the books of the Bible.
From 1672 to 1684, the date of his death, de Sacy published 10 additional books of the Bible. Using the manuscripts left by de Sacy, his friend Pierre Thomas (1634–1698) continued this task and undertook the publication from 1685 to 1693.
In 1696, La Sainte Bible contenant l'Ancien et le Nouveau Testament (the Holy Bible containing the Old and New Testaments) was published in 32 volumes.
