Henry Suso

Henry Suso, OP (also called Amandus, a name adopted in his writings, and Heinrich Seuse or Heinrich von Berg in German; 21 March 1295 – 25 January 1366) was a German Dominican friar and the most popular vernacular writer of the fourteenth century (when considering the number of surviving manuscripts). An important author in both Latin and Middle High German, he is also notable for defending Meister Eckhart's legacy after Eckhart was posthumously condemned for heresy in 1329. He died in Ulm on 25 January 1366, and was beatified by the Catholic Church in 1831.

Notable works: Minnebüchlein, Horologium sapientiae, Das Büchlein der ewigen Weisheit, Das Büchlein der Wahrheit, Vita, Sermons, Exemplar, Letters
