Judah Ben Samuel of Regensburg (12th & 13th Centuries), also called Hehasid or 'the Saint' in Hebrew. Was the initiator of Jewish mysticism in Germany, a way considered different from cabalistic mysticism because of how it insists more specific prayer and moral conduct. Hehasid settled in Regensburg in 1195. He wrote Sefer Hasidim (Book of the Pious) and Sefer Hakahod (Book of Glory), the latter has been lost and is only known by quotations that other authors have made from it.
