William Wells Brown spent the first twenty years of his life mainly in St. Louis and the surrounding areas working as a house servant, field hand, a tavern keeper's assistant, a printer's helper, an assistant in a medical office, and a handyman for James Walker, a Missouri slave trader. During his time with Walker, Brown made three trips up and down the Mississippi River. These trips allowed him to encounter slavery from every perspective and provided experiences he would draw on throughout his writing career.
