Joseph Barondess (July 3, 1867–June 19, 1928) was a labor leader and political figure in New York City's Lower East Side Jewish community in the late nineteenth century and early twentieth century. Known as the "King of the Cloakmakers", whose union he led, he carried himself like an actor, a career he had tried but failed at before he became a garment worker and union leader. In his heyday he was in great demand at public celebrations of all sorts; as one observer of the time noted, "It was almost a pleasure to die, knowing that Barondess would arrange the rites."
He was born in Bar, Ukraine in Vinnytsia region near Vinnytsia city and Kamenetz Podolsk city in Ukraine (former Russia). He was a son of Rabbi Judah Samuel Barondess. He was a relative of Supreme Court Justice Louis Brandeis Joseph Barondess may have spent time in Medzhibozh or perhaps he felt affiliated with the town because his wife came from there. Regardless, he was a lifelong member of the Medzhibozh landsmanshaftn society and helped support various members. He immigrated to England in 1885 where he met his wife Anna Zifels and came to the United States in 1888. After trying out with the Romanian Opera Company in New York, he went to work in the garment trade. Three years later Barondess helped found the Cloakmakers' Union. He also studied law for a time at New York University, but never finished his studies.
Barondess feuded with the Socialist Labor Party, which criticized him relentlessly. He formed a brief alliance with anarchists in the labor movement, but fell out with them as well. He eventually forged warmer relations with those socialists who left the SLP to form the Socialist Party.
