Black inventors for kids: 3 true picture books

Kids can meet three Black inventors and builders in true picture books: Madam C. J. Walker, the hair-care entrepreneur; Garrett Morgan, the inventor of the safety hood and a three-position traffic signal; and Patricia Bath, the inventor of the laserphaco cataract probe. Each Tumbly Inventors book is fact-checked against cited sources, written at three reading levels and read aloud.

Madam C. J. Walker

Hair-care entrepreneur · 1867–1919

Madam C. J. Walker (1867–1919) was a businesswoman who made hair-care products for Black women. Born Sarah Breedlove in Louisiana, she was the first child in her family born free. She built a factory in Indianapolis and trained thousands of women to sell her products and earn their own money.

The lesson: Solve a real problem, then teach other people to earn from it too.

Garrett Morgan

Inventor of the safety hood and a three-position traffic signal · 1877–1963

Garrett Morgan (1877–1963) was an American inventor and businessman in Cleveland, Ohio. The son of parents who had been enslaved, he invented a safety hood that let rescuers breathe in smoke and wore it in 1916 to rescue workers trapped in a tunnel under Lake Erie. In 1923 he patented a three-position traffic signal.

The lesson: When you see people in danger, build something that keeps them safe, even when others doubt you.

Patricia Bath

Inventor of the laserphaco cataract probe · 1942–2019

Patricia Bath (1942–2019) was an American eye doctor, laser scientist and inventor from Harlem, New York. She invented the laserphaco probe, a laser tool for removing cataracts, and in 1988 became the first Black woman doctor to receive a patent for a medical invention. She also started community ophthalmology, which brings eye care to people who could not get it.

The lesson: If one door is closed, find another, and keep working until you can help.
