CAMERARIUS, JOACHIM (1500-1574), German classical scholar, was born at
Bamberg on the 12th of April 1500. His family name was Liebhard, but he
was generally called Kammermeister, previous members of his family
having held the office of chamberlain (_camerarius_) to the bishops of
Bamberg. He studied at Leipzig, Erfurt and Wittenberg, where he became
intimate with Melanchthon. For some years he was teacher of history and
Greek at the gymnasium, Nuremberg. In 1530 he was sent as deputy for
Nuremberg to the diet of Augsburg, where he rendered important
assistance to Melanchthon in drawing up the Confession of Augsburg. Five
years later he was commissioned by Duke Ulrich of Wurttemberg to
reorganize the university of Tubingen; and in 1541 he rendered a similar
service at Leipzig, where the remainder of his life was chiefly spent.
He translated into Latin Herodotus, Demosthenes, Xenophon, Homer,
Theocritus, Sophocles, Lucian, Theodoretus, Nicephorus and other Greek
writers. He published upwards of 150 works, including a _Catalogue of
the Bishops of the Principal Sees_; _Greek Epistles_; _Accounts of his
Journeys_, in Latin verse; a Commentary on Plautus; a treatise on
Numismatics; _Euclid_ in Latin; and the Lives of Helius Eobanus Hessus,
George of Anhalt and Philip Melanchthon. His _Epistolae Familiares_
(published after his death) are a valuable contribution to the history
of his time. He played an important part in the Reformation movement,
and his advice was frequently sought by leading men. In 1535 he entered
into a correspondence with Francis I. as to the possibility of a
reconciliation between the Catholic and Protestant creeds; and in 1568
Maximilian II. sent for him to Vienna to consult him on the same
subject. He died at Leipzig on the 17th of April 1574.
