HARTMAN (John Adolphus), a learned divine and historian, was born at Munster in 1680. After being a Jesuit for several years, he became a Calvinist, at Cassel, in 1715, and soon after was made professor of philosophy and poetry, and in 1722 professor of history and eloquence at Marburg, where he died in 1744. The most esteemed of his works are, 1. The state of the sciences at Hesse, in German. 2. Historia Hassiaca, 3 vols. 3. Præcepta eloquentiæ rationalis, &c.
He ought not to be confounded with George Hartman, a German mathematician, who, in 1540, wrote a book on perspective; nor with Wolfgang Hartman, who, in 1596, composed the Annals of Augsburg.
