Andreae. I. Jakob, a German theologian, born at Waiblingen in Wurtemberg, March 25, 1528, died June 7, 1590. He studied at Stuttgart and Tubingen, and was ordained a pastor in the former town in 1540. In 1557 he became preacher to the court of Duke Christopher of Wurtemberg, whom he accompanied to the diets of Ratisbon and Frankfort. In 1562 he was appointed professor of theology and chancellor of the university at Tubingen, and provost of the church of St. George, and from this time took an important part in the movements and discussions of the Protestant church. He was particularly influential in securing the adoption of the Formula Concordia as the common profession of faith of the two Protestant parties.

II. Johann Valentin, a voluminous German author, grandson of the preceding, born at Herrenberg, Aug. 17, 1586, died in Stuttgart, June 27, 1654. After travelling over Germany, Switzerland, Italy, and France, he filled various ecclesiastical positions, and for some time officiated at the chapel of the duke of Wurtemberg. His Mythologia Christiana and some of his other Latin works, have been partly translated into German by Herder and Sonntag; and his Civis Christianus, site Peregrini quondam errantis Restitntiones (Strasburg, 1619), was translated into French under the title of Le sage Citoyen (Geneva, 1622). He published in 1633 a work advocating republican Christianity in Germany. His German writings include several poems; among others, Christlich Gemal (Tubingen, 1012), which is highly praised by Herder, who declares that Andrea) boldly announced truths in the 17th century which no one would dare to express in the 18th. He first made known the order of Rosicrucians in two or three publications, and is regarded by some as its founder or inventor; but this is denied by Herder. (See Rosicrucians.) His autobiography, in Latin, was published at Berlin in 1849.
