Yisroel Ber Odesser
Rabbi Yisroel Dov Ber Odesser (Hebrew: ישראל דב בער אדסר) (approx. 1898 – 23 October 1994), also known as Reb Odesser or Sabba ("grandfather" in Hebrew), was a Breslover Hasid and rabbi who claimed to have received a "Letter From Heaven" sent directly to him by Rebbe Nachman of Breslov, who had died 112 years earlier, revealing to him a new remedy for relieving the world's suffering and illness. This remedy is the song and name Na Nach Nachma Nachman Meuman, which he revealed in his old age to newfound followers throughout Israel. His following developed into the Na Nach movement. Some controversies surround the origin of the Letter, Rabbi Odesser's bold claims regarding Na Nach Nachma Nachman Meuman, and his position in the Breslov movement.
