Ludwig Haetzer (also Ludwig Hetzer, Ludwig Hätzer and sometimes Ludwig Hatzer) (1500 – 4 February 1529) was an Anabaptist.
He wrote against the uses of images in worship, translated some Latin evangelical texts regarding the conversion of Jews, and, together with Hans Denck, he translated the prophets of the Bible into German in 1528. Haetzer also wrote a booklet discouraging the consumption of alcohol. He regarded Jesus as a leader and teacher only; not divine and not an object of worship, therefore an anti-trinitarian and possibly a Unitarian.[1] He was eventually executed for his Anabaptist radicalism.
