a German theologian, noted in the department of exegesis, was born at Leipsic in 1734, and was educated at the university of that place. He afterwards held a professorship in his alma mater. He died there in 1803. His chief work is Obsersvationes ad Novum Testamentum. e Philone Alexandrino (Leipsic, 1777, 8vo). In this work "the force and meaning of words are particularly illustrated, together with points of antiquity, and the readings of Philo's text. The light thrown upon the New Testament by the writings of Philo is admirably elucidated by Losner" (Horne). Another valuable production of his is Observationes in reliquias versionis Proverbiorum Salomonis Graecae Aquilae, Symmachi et Theodotionis.
