Rozen, Yoysef
February 13, 1894–April 30, 1954
He was born in Jedwabne, Poland. He studied in religious elementary schools, later in Magnus Krinski’s commercial school in Warsaw. He studied law at Warsaw University. He lived for a short time in Lodz, Poltava, and Kovno, and he was one of the leaders of the left Labor Zionists in Poland—and from 1932 in Israel.
He wrote articles about ideology and practice of the left Labor Zionists in the party publications: Arbayter Tsaytung (Workers’ Newspaper) in Kovno (1920, also its editor), Arbeter-Tsaytung (Labor Newspaper), Di Fraye Yugnt (Free Youth) in Warsaw (using the pen names of Yoysef, Doron, and Davidovitsh, among others), and Fraye Yugent (Free Youth) in Warsaw (1921, also editor).
He wrote a series of militant party pamphlets, especially against the Bund and the Yevsektsye (Jewish Section [in the USSR]):
Krimer Teritoryalizm un Proletarisher Palestinizm (Crimean Territorialism and Proletarian Palestinism) (Warsaw, 1926), 64 pp. (twentieth printing);

With Z. Abramovitsh and Zerubavl, he edited Fun Britishn Mandat biz der Yidisher Medine (From the British Mandate to the Jewish State) (Buenos Aires, 1954).
He placed longer articles in: Dos Arbeter-Palestina (The Workers’ Palestine) (Warsaw, 1925), mostly using the pen name Yoysef. In 1957 there appeared in print his Ketuvin nevaḥim (Selected Works) (Tel Aviv), 383 pp.
Under the name Y. Rozen, there is a translation of the Passover Haggadah, with the prayers and customs of Passover, Hebrew and Yiddish on opposing pages (Buenos Aires: A. Sigal, 1950), 34 pp. It is clear that this is the work of someone else.
He died in Tel Aviv.
