There is arguably no greater figure in Talmudic literature than that of Hillel the Elder. He combined the Torah leadership of Moshe Rabbeinu with Aharon's peace-making and love for all. It is not by chance the Talmud teaches that if not for Hillel, Torah would have been forgotten from amongst the Jewish people (Sukkah 20a).
One of the most famous Talmudic stories is that of the potential convert who conditioned his conversion on whether or not he could be taught the Torah while standing on one foot. Shammai, bothered by the chutzpah of this non-Jew (imagine going to a nuclear physicist and asking to learn all of physics while standing on one foot!), “pushed him with the construction board in his hand”. Hillel, non-plussed by this ludicrous request, simply answered, “What is hateful to you, do not do to others; all the rest is commentary. Go and learn”.
