For the uninitiated the subject of moral reform appears to be a topic best suited for examining the traditional view of the Latin American woman: that of a female preoccupied with sin and salvation and with no interest in the world outside the home or increased rights for her sex. Closer investigation reveals, however, that moral reform movements often have indicated women's active presence and concern about the direction of a nation's social policies and customs. (Addams, 1912: 160-195; Davis, 1973; Smith-Rosenberg, 1971: 381-385, 562-564). Involvement in moral reform activities often but not always has meant that a woman considered herself a feminist and believed that the goals of these two movements were inextricably linked together. In order to explore these two hypotheses, this essay will focus on Paulina Luisi (1875-1950), an Uruguayan doctor whose lifelong dedication to moral reform and feminism earned her an international reputation as a fighter for one sexual moral standard and women's rights (Mapons, 1950; Scarone, 1937: 284-289). Examining her extensive writings and many projects provides an excellent insight into two movements which claimed the loyalty of numerous women activists, both bourgeois and socialist, in Latin America, Europe, and the United States (Addams, 1912; Chataway, 1962; Lloyd, 1971; Luisi, 1948). Given the Latin American context and the time period, Luisi can be seen as a major figure in the international feminist and moral reform movements.
