Black Innovators Who Electrified the World
Electricity powers nearly every part of modern life, from lighting and transportation to communication, medicine, and technology. Yet many of the innovators who helped develop electrical systems and energy solutions have been overlooked or left out of traditional history lessons.
Black inventors, engineers, and scientists have played a vital role in advancing electricity and energy technology, often while overcoming limited access to education, funding, and professional recognition. Their work continues to influence how electricity is generated, stored, and used today.

Take Away
Together, these innovators demonstrate that progress in electricity has always depended on diverse thinkers and problem solvers. Their work highlights perseverance, creativity, and scientific excellence in the face of barriers.
Teaching these stories helps expand historical understanding and encourages future generations to see themselves as scientists, engineers, and inventors.
Electricity did not evolve through the work of one individual or one generation. It advanced through the ideas and determination of many innovators, including Black pioneers whose contributions continue to shape the modern world.
Their work still powers our lives today.
