Landsperger, Johann, a Carthusian monk, who obtained distinction by his voluminous ascetic writings, was born in Landsperg, Bavaria, in the latter part of the 15th century; studied in Cologne, was made prior of his order near Julich, and died about 1534. On account of his marked and severe piety, he was called the Just. Among his works, which were published in many editions at Cologne, are, Sermones capitulares in praecipuis anni festivitatibus: — Vita Servatoris N.I.X.: — Paraphrases in dominicales Epistolas et Evangelia: — Alloquia Jesu Christi ad fidelem adnimam: — Enchiridion vitae spiritualis ad perfectionem: — Pharetra divini amoris. Landsperger was the first to publish the Revelations of the Holy Gertrude. — Wetzer u. Welte, Kirchen-Lexikon, 6:342.
