Malach moved to
Warsaw in 1907 at the age of 13, working several odd jobs as a mirror cutter, baker, housepainter, and wallpaperer. He took an interest in writing from Yiddish newspapers and theatre at the age of 16.
Hersh Dovid Nomberg helped start his writing career, beginning with the ballad
Three in 1915. He took the surname Malach from his mother's first husband, and continued writing songs and ballads, before turning to novels and plays. He was published in several Yiddish newspapers in Warsaw,
Łódź, and
Lublin:
Varshever tageblat,
Haynt,
Der Moment,
Lodzer folksblat,
Lodzer tageblat, and
Lubliner togblat. He became involved in
Labor Zionism and wrote the oath of their youth movement. This made him popular among Jews in Warsaw and all over Poland, and he was frequently asked to speak and present his work. Returning to Radom in 1921, he became a newspaper editor. He published two books and two children's plays in 1922 before moving to
Argentina that year. ==Abroad, return, and death==
