Peter Baro (1534–1599) was a French Huguenot minister, ordained by John Calvin, but later in England a critic of some Calvinist theological positions. His views in relation to the Lambeth Articles cost him his position as Lady Margaret's Professor of Divinity at the University of Cambridge. He was a forerunner of views, to be called Arminian or Laudian, more common a generation later in England.
He was son of Stephen Baro and Philippa Petit, his wife, and was born December 1534 at Étampes. Destined for the study of civil law, he entered the University of Bourges, where he took his degree as bachelor in the faculty of civil law 9 April 1556. In the following year he was admitted and sworn an advocate in the court of the Parliament of Paris.
In December 1560 he moved to Geneva, and was admitted to the ministry by Calvin. Returning to France he married, at Gien. Guillemette, the daughter of Stephen Bourgoin, and Lopsa Dozival, his wife. He emigrated to England, where he was befriended by Lord Burghley, who as chancellor of the university of Cambridge, exercised his influence on Baro's behalf. He was admitted a member of Trinity College where John Whitgift was then master. The Provost of King's College, Roger Goad, engaged him to read lectures in divinity and Hebrew. In 1574, through the influence mainly of Burghley and Andrew Perne, he was chosen Lady Margaret professor of divinity. In 1576 he was created D.D., and was incorporated in the same degree at Oxford on 11 July.
