One notable self-made millionaire in Black history is Madam C.J. Walker. Born Sarah Breedlove in 1867, she was an African American entrepreneur, philanthropist, and social activist. Madam C.J. Walker is widely recognized as the first female self-made millionaire in America, regardless of race.

She became a successful businesswoman by creating a line of hair care products specifically designed for Black women. Walker developed her products to address the needs of African American women who were experiencing hair loss and scalp issues due to the limited availability of products tailored to their hair textures.

Through her company, the Madam C.J. Walker Manufacturing Company, she built a vast network of sales agents who sold her products door-to-door, providing opportunities for Black women to become financially independent and build their own businesses. Walker's entrepreneurial success and commitment to empowering Black women made her a trailblazer in the business world and a prominent figure in Black history.

Madam C.J. Walker also used her wealth to support charitable causes and organizations that uplifted the Black community. Her legacy continues to inspire generations of entrepreneurs, especially women of color, to pursue their dreams and create their own paths to success.
