"Feminist writers, not trained historians, were the first to undertake a systematic attempt to approach the problem of women's role in American life and history. This took the form of feminist tracts, theoretical approaches, and compilations of woman's "contributions." The early compilers attacked the subject with a missionary zeal designed, above all, to right wrong. Their tendency was to praise anything women had done as a "contribution" and to include any women who had gained the slightest public attention in their numerous lists. Still, much positive work was done in simply recounting the history of the woman's rights movement and some of its forerunners and in discussing some of the women whose pioneering struggles opened opportunities to others. Feminist writers were hampered by a two-fold bias. First, they shared the middle-class, nativist, moralistic approach of the Progressives and tended to censure out of existence anyone who did not fit into this pattern. Thus we find that women like Frances Wright and Ernestine Rose received little attention because they were considered too radical. "Premature feminists" such as the Grimké sisters, Maria Weston Chapman, and Lydia Maria Child are barely mentioned."
