Throughout U.S. history, black women have founded businesses, transformed industries, revolutionized television and media and created jobs — often without recognition.
Black women are the second fastest-growing group of entrepreneurs, after Latina women.
According to the 2016 State of Women-Owned Businesses Report, "there are an estimated 1.9 million African-American women-owned firms, employing 376,500 workers and generating $51.4 billion in revenues."
Here are 14 black women whose contributions impacted business, finance and the U.S. economy:
1. Ursula Burns
Burns is the chairwoman of Xerox and served as CEO through 2016. Early in her time Xerox, Burns publicly disagreed with a company vice president. She thought she'd be fired but the risky move paid off; Burns moved into an executive assistant role that introduced her to the c-suite and changed the course of her career.
2. Beyoncé Knowles-Carter
Known as "Queen Bey" to fans, the global music and entertainment icon has taken home 20 Grammy awards and is worth an estimated $290 million. In her 2016 hit "Formation" she called herself a "black Bill Gates in the making."
3. Carla Harris
Harris is the vice chairman of wealth management at Morgan Stanley and a senior client advisor for the financial giant. The influential Wall Street exec was appointed by President Barack Obama chair of the National Women's Business Council in 2013.
"Don't be distracted by anything anybody else tells you," Harris tells CNBC.
4. Janice Bryant Howroyd
As a teenager, Howroyd was one of the first black students to attend her North Carolina hometown's previously segregated high school. As founder and CEO of staffing agency ACT-1, she became the first black woman to own a billion-dollar company. ACT-1 is also the largest certified woman-minority-owned staffing agency in the U.S.
When she started out, she tells CNBC, all she had was a "brain, a phone and a phonebook."
5. Madam C.J. Walker
In the early 1900s, Sarah Breedlove, better known as Madam C.J. Walker, turned her line of homemade hair care products into an eponymous business empire that's still active today. At the time of her death she was widely recognized as the first self-made female millionaire in the U.S.
"Don't sit down and wait for the opportunities to come," Walker once said. "Get up and make them."
6. Tyra Banks
Besides being a supermodel, Banks is an entrepreneur who changed the beauty business. She created the hit TV show "America's Next Top Model," starred in an Emmy-award winning talk show and launched a beauty company.
The questions that motivate her, she tells CNBC, are "What hasn't been done before? What is there to conquer? What is there to innovate? What is there to create?"
7. Tina Wells
Wells is the CEO and founder of Buzz Marketing Group, which works with major clients like Dell and Levo. She is a member of the United Nations Foundation Global Entrepreneurs Council and is the academic director of Wharton's Leadership in the Business World program, a program for high school students.
