Walker Manufacturing Company, which became one of the most successful African American-owned businesses of the early 20th century.

After experiencing hair loss, Walker developed a line of hair care products specifically designed for Black women, which included the famous "Wonderful Hair Grower." She traveled around the United States promoting her products and teaching other Black women about entrepreneurship and financial independence.

Walker's legacy as a pioneering entrepreneur and advocate for social change has had a lasting impact on Black history and continues to inspire generations of Black women and entrepreneurs today.
