Samuel of Speyer
Samuel ben Kalonymus he-Hasid of Speyer (Hebrew: שמואל החסיד; 1120–1175), was a Tosafist, liturgical poet, and philosopher of the 12th century, surnamed also "the Prophet". He seems to have lived in Spain and in France. He was the first of the Chassidei Ashkenaz, and the father of Judah ben Samuel of Regensburg.
According to legend, he created a golem which accompanied him on his travels and served him, but could not speak.
