Camerarius. I. Joachim, a German scholar, born at Bamberg, April 12, 1500, died in Leip-sic, April 17, 1574. His proper name was Liebhard, which he changed into Camerarius, in honor of the office of chamberlain which his ancestors held at the court of the bishop of Bamberg. Educated at Leipsic and Erfurt, his attention was arrested by the writings of Me-lanchthon, and in 1521 he went to Wittenberg to make the acquaintance of that reformer. From this time his life and influence were identified with the reformation. In 1526 he was appointed teacher at Nuremberg, and was afterward sent to the university of Tubingen. The dukes of Saxony, a few years later, employed him to remodel the Leipsic university, of which he afterward became rector. He was at the diet of Augsburg, and gave important aid in drawing up the Augsburg confession; and when in 1555 the diet assembled there again, Camerarius continued a prominent delegate, and in the year following was at Ratisbon in the same capacity. He was soon after called to Vienna by the emperor Maximilian II. to counsel in the critical affairs of the empire in regard to religion. Camerarius was a scholar of extensive and varied learning.

He cultivated medicine, mathematics, and Greek. His works (more than 150 distinct treatises) are mostly on classical and religious subjects. He translated into German many Greek and Latin authors. His biography of Melanchthon (Leipsic, 1592), of which a new edition appeared in Halle in 1777, and his collection of letters of that reformer, are peculiarly interesting to the student of the reformation. II. Joachim, son of the preceding, born at Nuremberg, Nov. 5, 1534, died there Oct. 11, 1598. He was sent successively to Wittenberg and Leipsic, and also studied with Melanchthon, and received a medical diploma at Bologna in 1562. Botany was his favorite study. A genus of plants (Cameraria) was named after him. III. Rudolph Jakob, a German physician and botanist, born in Tubingen, Feb. 17, 1665, died there, Sept. 11, 1721. He was professor of medicine and director of the botanic garden at Tubingen, and was the first to observe the male and female generative organs in plants, and to establish the true sexual theory of plants.

His principal work is Epistolae de Sexu Plantarum (Tubingen, 1694 and 1749).
