Hillel the Elder
He was a leader of the Pharisees in the 1st century BCE and president of the Sanhedrin before the reign of Herod the Great. He and his colleague Abtalion are termed the "gedolei ha-dor" (the great men of the age) and "darshanim" (exegetes). Hillel the Elder was a contemporary of Shemaiah and Abtalion, and regularly attended their lectures.
