In 1848, Mary Walker was born into slavery. At age 15, she was freed, and by age 20, she was married and had her first child. By age 68, she had worked numerous jobs, including cooking, cleaning, babysitting, and selling sandwiches to raise money for her church. At 114, she was the last remaining member of her family. And at 116, she learned to read.
