Shmaryahu Noah Schneersohn (1842-1923) was the fourth and last rebbe of Kopust, a branch of the Chabad dynasty of Hasidism. He succeeded as 4th leader of the group after his brother, Shalom Dovber Schneersohn, died.[1] Other sources say he succeeded his brother, Shlomo Zalman Schneersohn, as leader of the group in the year 1900 after Shlomo Zalman died.[2][3][4][5] He served as the Kopuster movement's rebbe in the town of Babruysk.[6] He was rabbi of the chasidim in Babruysk from 1872, and founded a yeshiva there in 1901.[7] He authored a two-volume work on Hasidism, titled "Shemen LaMaor" ("Light for the Luminary").[2][4][5]
