Nachman Chazan (1813–1884) was a seminal figure in the continuation and growth of Breslov Hasidism in the mid-nineteenth century.
Rebbe Nachman's closest disciple, Nathan of Breslov (also known as "Reb Noson"), shaped and shepherded the movement until his own death in 1844.
Chazan was an extremely modest man whose actions belied his greatness in scholarship and spiritual devotions.
He served as the shammes (sexton) of the Breslover synagogue in Uman and regularly filled the water buckets for the benefit of other worshipers.
In recognition of his leadership, however, he was accorded the honor of leading the prayers at the annual Rosh Hashana kibbutz in Uman.
