Helen Marguerite (Emery) Roberts (January 20, 1896 – June 22, 1983) was an American writer, photographer, and multilingual educator. From 1958 to 1975, she battled illiteracy in Africa, teaching reading, writing, health and Christian religion to thousands of illiterate adults. In the course of her African work, she mentored and sponsored many promising young Africans, encouraging them to pursue higher education, including Barack H. Obama, the father of President of the United States Barack Obama.
