Nathan Sternhartz

Main disciple of R. Nachman of Breslov and leader of the movement after his death. However, he did not actually assume his teacher's position as Rebbe of Breslov, being that R. Nachman had not named a successor. R. Nathan is the one responsible for preserving R. Nachman's teachings by recording, publishing, and disseminating them. He also authored many of his own works, including the multivolume "Likutei Halakhot," an esoteric work which follows the order of the Shulchan Arukh.
