Yohanan ben Zakkai
Yohanan ben Zakkai was a Jewish sage of the first century of the common era, and a primary contributor to the core text of rabbinic Judaism, the Mishnah. He was an important sage in the era of the Second Temple in Jerusalem, and re-established the Sanhedrin after the destruction of the Temple in 70 C.E.
The core works of Judaism's oral law often conflate fact, myth and legend, and are often unrelibale, or even silent, on precise historical details. The Mishnah offers no information on his birth or family. He is recorded as living until the age of 120 years.
He is said to be a pupil of Hillel. He is known to have studied in Jerusalem, in the Land of Israel, and then went to the Galilee.History
