What was Madam cj Walkers education?

Madam Walker, who was born Sarah Breedlove in Delta, Louisiana in 1867, grew up during an era when the Louisiana state legislature and local parish governments refused to appropriate funds for public education for black children. She received very little formal education as a child, but is believed to have learned rudimentary reading and arithmetic in her family church where Curtis Pollard was the minister. Later, after she and her daughter moved to St. Louis in the late 1880s, she began to learn from her daughter, who attended the public schools there, and from some of the women in her church at St. Paul AME. She later said she attended night school to learn more. After she began to be successful in her hair care business, she hired a personal tutor. She had a thirst for knowledge and was very interested in current affairs and history. She was considered a "self-taught" or "self-educated" person as were many accomplished people during an era when American public school education was spotty in many parts of America and when only a few thousand people a year graduated from college in America.
