Baruch Charney was born January 13, 1886, in Dukor, a small village near Minsk, in what is now Belarus. His parents were Zev Volf and Brokhe Tsharni. His father, a fervent LubavitcherHasid, died in 1889, leaving his mother a widow with five sons and a daughter. Two of his older brothers also achieved renown: literary criticShmuel Niger and Yiddish poet Daniel Charney. In the early 1900s, Baruch Charney was drawn to the revolutionary movement for the overthrow of the Tsarist autocracy, becoming an activist in the Jewish Labour Bund. As an underground revolutionary, open use of his real name was regarded as highly dangerous to both him and his family, so the pseudonym "Vladeck" was adopted as a nom de guerre. Baruch Charney would use this as his surname for the rest of his life. Vladeck was arrested in 1904 for conducting a radical study circle for young workers, and was imprisoned for a total of 8 months as a result of this first arrest. He was arrested again in 1905 and faced an extensive exile in Siberia, a fate from which he was saved by the outbreak of the Revolution of 1905 and the political amnesties which accompanied that seminal event. The 1905 revolution ended in Tsarist restoration by 1907 and a period of reaction ensued. Vladeck came to feel that emigration to the United States was his most realistic option. In 1908 he left Europe for North America, landing at Ellis Island, soon after which he began to immerse himself in the study of American history and culture.
In America, Vladeck made use of his previous experience as a public speaker, traveling extensively for four years and giving public lectures on a variety of social, political, and economic topics. Vladeck joined the staff of the socialistThe Jewish Daily Forward in 1912 as manager of its Philadelphia branch while also studying at the Teachers' College of the University of Pennsylvania. In 1918 he became manager of the paper, and remained in that position until his death in 1938. He was also a member of the National Press Club. In 1917 Vladeck was elected to the New YorkBoard of Aldermen as a Socialist. He was defeated in 1921 but was re-elected in 1937 to the newly formed New York City Council running on the American Labor Party ticket. Vladeck was also at the forefront of establishing public housing for low-income residents and in 1934 was named by Mayor LaGuardia to the New York City Housing Authority. In 1933 Vladeck laid the groundwork for the Jewish Labor Committee, which was formed by Jewish trade unionists, socialists, and kindred groups and individuals to oppose the rise of Nazism in Germany. The JLC had its founding convention the following February, in New York's Lower East Side; Vladeck was the organization's president from the convention until his death. He, together with Jewish trade union leaders, successfully convinced the American Federation of Labor to support a national boycott of German goods at the labor federation's 1933 convention.
