The study of the history of the Seventh-day Adventist Church and the development of its evangelistic expansion has given poor emphasis on women contribution to church leadership and missionary work. More specifically, the participation of women in the presidency of Conferences has not been addressed in previous historical works, except the brief mention of the subject by Kitt Watts. The goal of this article is to fill this gap in the study of Adventist missiological history. On this purpose, it is described the life and work of Flora Plummer, Petra Tunheim, Hanna John Lutz, Emma Rodriguez, Marie Joswig Fanselau and Phyllis Mosley Ware; six women who have served as acting presidents of Adventist Conferences.
