Moshe de León

R. Moshe ben Shem Tov de León (c. 1240-1305) is — by the consensus of modern academic scholarship from Scholem through Liebes, Abrams, and Idel — the principal author of the Zohar, the foundational text of theoretical Kabbalah. Born in León (Castile), he lived in Guadalajara and Ávila in the 1280s-1290s, the very years in which the Zoharic corpus was composed.

He also produced a substantial body of independently-signed works including Mishkan HaEdut (1290), Shekel HaKodesh (1292), Sefer HaRimmon, Sefer HaShem, Or Zarua, and She'elot u-Teshuvot — many of which share distinctive vocabulary, themes, and theological patterns with the Zohar. His Zoharic authorship is traditionally contested (most Orthodox communities still affirm the pre-modern attribution to R. Shimon bar Yochai), but the literary fingerprints are extensive.
