Heinrich Klee (b. Münstermaifeld, in the Rhine province, 20 April 1800; d. Munich, 28 July 1840) was a German theologian and Biblical exegete who argued against liberal and Rationalist currents in Catholic thought.
At the age of seventeen he entered the seminary at Mainz. In 1824, a year after his ordination, he was appointed to the professorship of exegesis and ecclesiastical history in the same seminary, and in the following year also to that of philosophy. In the meantime he obtained the Doctorate of Theology from the University of Würzburg after presenting the thesis Tentamen theologico-historicum de chiliasmo primorum saecolurum. In 1829 the government of Baden tendered him the chair of exegesis at Freiburg, vacated by Johann Leonhard Hug, and at the same time the Prussian authorities offered him a professorship either at Breslau or Bonn.
He chose Bonn; but his position there was a difficult one. George Hermes and his ideas were strong there, and the presence of Klee, an exponent of orthodox Catholicism, was viewed with disfavour by his Rationalist colleagues. After ten years' stay at Bonn, during which he taught dogmatic and moral theology, the history of dogma and exegesis, Klee was induced by the conflict between the Archbishop von Droste-Vichering of Cologne and the Hermesian professors to accept the call to the University of Munich as successor to Mö in the chair of dogmatic theology and exegesis, but an early death carried him off within a year.
