Mary Antin (born Maryashe Antin; June 13, 1881 – May 15, 1949) was an American author and immigration rights activist. She is best known for her 1912 autobiography The Promised Land, an account of her emigration and subsequent Americanization. Mary Antin was the second of six children born to Israel and Esther Weltman Antin, a Jewish family living in Polotsk, in the Vitebsk Governorate of the Russian Empire (present-day Belarus). Israel Antin emigrated to Boston in 1891, and three years later he sent for Mary and her mother and siblings.[3] The family moved from Chelsea to Ward 8 in Boston's South End, a notorious slum, as the venue of Israel's store changed. She attended Girls' Latin School, now Boston Latin Academy, after finishing primary school.[citation needed] She married Amadeus William Grabau, a geologist, in 1901, and moved to New York City where she attended Teachers College of Columbia University and Barnard College. Antin is best known for her 1912 autobiography The Promised Land, which describes her public school education and assimilation into American culture, as well as life for Jews in Czarist Russia. After its publication, Antin lectured on her immigrant experience to many audiences across the country, and became a major supporter for Theodore Roosevelt and his Progressive Party.[citation needed] During World War I, while she campaigned for the Allied cause, her husband's pro-German activities precipitated their separation and her physical breakdown. Amadeus was forced to leave his post at Columbia University to work in China, where he became "the father of Chinese geology." She was never physically strong enough to visit him there. During World War II, Amadeus was interned by the Japanese and died shortly after his release in 1946. Mary Antin died of cancer on May 15, 1949.[1][2] Less
