Johann Pistorius

Johann Pistorius (14 February 1546 – 19 June 1608), also anglicized as John Pistorius or distinguished as Johann Pistorius the Younger, was a German controversialist and historian. He is sometimes called Niddanus from the name of his birthplace, Nidda in Hesse.

Life

His father was a well-known Protestant minister, Johann Pistorius the Elder (died 1583 at Nidda). From 1541 he was superintendent or chief minister of Nidda, and took part in several religious disputations between Catholics and Protestants.

Pistorius the Younger studied theology, law, and medicine at Marburg and Wittenberg 1559-67. He received the degree of Doctor of Medicine, and in 1575 was appointed court physician to the Margrave Karl II of Baden-Durlach, who frequently sought his advice in political and theological matters. Pistorius turned from Lutheranism to Calvinism; through his influence the Margrave Ernst Friedrich of Baden-Durlach made the same change.

As time went on, however, Pistorius became dissatisfied with Calvinism also. In 1584 he became a privy councillor of Margrave James III of Baden-Hochberg at Emmendingen; after further investigation he entered the Catholic Church in 1588. At his request the Margrave James brought about the religious disputations of Baden, 1589, and Emmendingen, 1590. After the second disputation the court preacher Zehender and the margrave himself became Catholics. James III, however, died on 17 August 1590, and being succeeded by his Protestant brother Ernst Friedrich, Pistorius was obliged to leave.
