Henri Spondanus (de Sponde) (born at Mauléon, in the French Department of Basses-Pyrénées, January 6, 1568; died at Toulouse, May 18, 1643) was a French Catholic jurist, historian and continuator of the Annals compiled by Cardinal Baronius, and Bishop of Pamiers. He was a convert from Calvinism.
After studying humanities at the Calvinist college of Orthez, he accompanied the royal ambassador to Scotland and, upon his return, took up the study of jurisprudence. In 1589 he was jurist at the Parlement of Tours.
Convinced by the writings of Robert Bellarmine and the instructions of Duperron, he became a Catholic, 21 September 1595. In 1600 he accompanied Cardinal François de Sourdis to Rome, where he was ordained priest on 7 March 1606; Pope Paul V then appointed him reviser of the briefs of the Apostolic Penitentiary.
In 1625 he was created Bishop of Pamiers. He labored for the preservation of Catholicism and converted numerous Protestants. Owing to ill-health, he resigned his diocese in 1639 and retired to Toulouse.
