Whatever else he was, Abraham Cahan was a lifelong socialist. As a critic, he helped to shape the literary and theatrical tastes of the Yiddish-speaking immigrants. As a novelist, he interpreted the immigrant community to the English-speaking public. But it was his role as editor in chief of the largest socialist daily in the United States, from a time when the movement seemed to have a bright future, that made him a force to be reckoned with in the Jewish community, New York City and beyond. As editor, Cahan put his newspaper at the service of social justice for the poor, the working people and the immigrants. Even when youthful utopianism gave way to middle-aged pragmatism, he recognized that unfettered capitalism failed to provide for a fair distribution of power and wealth.
