Ber Borochov

Dov Ber Borochov (Russian:Дов-Бер Борохов; July 3, 1881 – December 17, 1917) was a Marxist Zionist and one of the founders of the Labor Zionist movement as well as a pioneer in the study of Yiddish as a language.
He was born in the town of Zolotonosha, Russian Empire (currently in Ukraine). As an adult he joined the Russian Social Democratic Labor Party but was expelled when he formed a Zionist Socialist Workers Union in Yekaterinoslav. Subsequently, he helped form the Poale Zion party and devoted his life to promoting the party in Russia, Europe, and America. When the Russian social democrats came to power, Borochov returned to Russia in March 1917 to lead the Poale Zion. He became ill and died in Kiev of pneumonia in December 1917.
