David Dubinsky (; born David Isaac Dobnievski; February 22, 1892 – September 17, 1982) was a Belarusian-born American labor leader and politician. He served as president of the International Ladies Garment Workers Union (ILGWU) between 1932 and 1966, took part in the creation of the CIO, and was one of the founders of the American Labor Party and the Liberal Party of New York. Early life and career in Russia David Isaac Dobnievski was born February 22, 1892, in Brest, in what was then the Russian Empire (and is now Belarus), as the youngest of five boys and three girls. Dubinsky and his family moved to Łódź, Poland, shortly before he turned three. David's father, Bezalel Dobnievski, a religious Jew, owned a bakery, but limited himself to administrative tasks related to the enterprise. David's mother Shaina Wyshengrad died when he was eight, with his father remarrying a year and a half later. David worked from early childhood delivering bread from his father's bakery to local shops, while attending a Hebrew school, where he studied Polish, Russian, and Yiddish. He was later forced to leave a semi-private school he attended to take work in his father's bakery to replace a brother who had left abruptly. Early union activity, arrest, and emigration to United States During the 1905 Russian Revolution, Dubinsky attended a mass meeting which led to his kinship, if not actual membership, with the General Jewish Labor Bund, a Jewish socialist labor organization. He joined the bakers' union, which was controlled by the Bund, and owing to his superior education and fluency in several languages, was elected assistant secretary within the union by 1906. By age 15, he was leader of the local labor union. In 1906 or 1907, Dubinsky was arrested by the Okhrana, and was held for 18 months in prison before being sentenced to hard labor in Chelyabinsk, Siberia upon reaching the age of 16. On the way to Chelyabinsk, however, he escaped containment and fled to the United States, landing in New York City in 1911, at the age of 19. Early career in the United States Joining the ILGWU When Dubinsky came to the United States in 1911, he began by working as a dishwasher. He quickly rose to become a sewing machine operator, but ignored requests from relatives that he pursue a career in the medical industry, and did not join his brother as
