Henry Suso was a fourteenth-century German Dominican friar and a highly influential mystic. Born into the noble Berg family in Constance, he later adopted his mother's surname, Sus, to demonstrate humility. He entered the Dominican Order at age thirteen and became a significant theologian and poet, writing extensively in both Latin and Middle High German. Suso is particularly noted for his spiritual writings and for defending the theological legacy of Meister Eckhart during a period of intense scrutiny within the Church.
