Rose Schneiderman, the daughter of Jewish parents, was born in Saven, Poland, 1882. When Rose was eight years old her family emigrated to the United States. After the death of her father, Rose and her brothers and sisters were brought up in various orphanages.
At thirteen Rose was forced to go out to work: "I got a place in Hearn's as cash girl, and after working there three weeks changed to Ridley's, where I remained for two and a half years. I finally left because the pay was so very poor and there did not seem to be any chance of advancement, and a friend told me that I could do better making caps."
She eventually went to work in a factory in search of higher wages: "After I had been working as a cap maker for three years it began to dawn on me that we girls needed an organization. The men had organized already, and had gained some advantages, but the bosses had lost nothing, as they took it out on us. Finally Miss Brout and I and another girl went to the National Board of United Cloth Hat and Cap Makers when it was in session, and asked-them to organize the girls. Then came a big strike. About 100 girls went out. The result was a victory, which netted us - I mean the girls - $2 increase in our wages on the average."
Rose developed radical political views and became an active socialist and trade unionist. She also joined the campaign for women's suffrage. In 1903 she founded the Jewish Socialist United Cloth Hat and Cap Makers' Union. This was the start of a long career in which she eventually became president of the Women's Trade Union League.
