Simeon ben Yohai, Rabbi

Simeon ben Yohai, Rabbi: (c. 100-160 CE) Mishnaic sage and mystic, student of Rabbi Akiba. When he evoked the wrath of the Roman authorities, he, together with his son Eleazar, hid in a cave for thirteen years, where their needs were miraculously provided for. He authored the Zohar, the most fundamental kabbalistic work. The anniversary of his passing, the 18th of Iyar, known as Lag BaOmer, is celebrated every year, as per his request.
