Rabbi Hillel the Elder. Renowned in the Jewish tradition as a sage and a scholar, he is associated with the development of the Mishnah and the Talmud and, as such, one of the most important figures in Jewish history. Asked for a summary of the Jewish religion in the most concise terms, Hillel replied (reputedly while standing on one leg): "That which is hateful to you, do not do to your fellow. That is the whole Torah. The rest is the explanation; go and learn."
