Shmuel Vulman (1896-1941) was born in Kałuszyn, near Warsaw into a poor Hassidic family. He moved to Warsaw in 1917, and became active in the left Labour Zionists. He published poetry in many Yiddish journals, wrote a number of popular books, and also translated works from other languages into Yiddish.
When the Nazis invaded Poland, he escaped to Białystok which was under Soviet rule, and was persecuted for his prior critical attitude toward Bolshevism. When the Nazis invaded Russia, he moved to Kremenits (in modern Ukraine), where he was killed by the Nazis along with fellow writers Sh. Zaromb and Yerakhmiel Nayberg.
Vulman also published under the names: Y.-Sh. Prager, Sh.-Z. Vulf, L. (Leyzer) Felzner, Sh. V. Man, A. Masholnu, Sh. V., and Shin-vov, among others.
