Apel, Johann a German theologian, was born at Nuremberg in 1486. After having studied theology at the university of Wittenberg, he became canon at Wurzburg, where he married a nun in 1523, in consequence of which he was expelled. He was one of the most zealous adherents of Luther, and eagerly labored for the spreading of the Reformation. He died in 1536 at Nuremberg, where he had been, during the last years of his life, jurist of the republic and councillor of the elector of Brandenburg. He wrote, among other works, Defensiao po suo conjugia cum praefat. Lutheri (Wittenb. 1523, 4to); Brachylogus juris civilis, sive corpus legaum: a work long ascribed to the Emperor Justinian. — Hoefer, Biog. Generale, 2, 875.
