Johann Hermann Janssens (b. at Maaseik, present-day Netherlands, 7 December 1783; d. at Engis, 23 May 1853) was a Belgian Roman Catholic theologian.
[1] After completing his theological studies in Rome he was appointed professor in the College of Fribourg, Switzerland, in 1809.
Shortly afterward, and against the will of his ecclesiastical superiors, he accepted the chair of anthropology and metaphysics in the philosophical college of the Catholic University of Leuven.
[1] His international reputation rested mainly on his first publication, "Hermeneutica Sacra seu Introductio in omnes et singulos libros sacros Veteris et Novi Foederis."
A French translation of this work, the original of which had reached its nineteenth edition in 1897, was published by Pacaud as early as 1828.
