National Inventors Month is a time to honor those who dream boldly and push through doubt to create with courage. Innovation has never been the work of a select few. Women, especially women whose names don’t always appear in textbooks, have long been at the forefront of scientific and technological breakthroughs. This month, we’re celebrating three visionary women whose inventions opened doors for entire disciplines and those who came after them.

Maria Telkes: The Queen of Solar Power

Maria Telkes, a Hungarian-American scientist, brought solar power into the modern age. In 1947, she created the first thermoelectric power generator, harnessing heat to generate electricity using semiconductor materials. But she didn’t stop there.

Telkes went on to design the first solar heating system for a home, the Dover Sun House in Massachusetts, proving that renewable energy could support everyday life. She also invented the first thermoelectric refrigerator in 1953, a breakthrough that offered refrigeration without needing moving parts or harmful gases.

Her work laid the foundation for today’s clean energy industry and showed that science and sustainability could live side by side.

Dr. Patricia Bath: Visionary in Every Sense

Dr. Patricia Bath was a barrier-breaker. As the first Black woman doctor to receive a medical patent, she created the Laserphaco Probe, a device that revolutionized cataract surgery by making it faster, more precise, and safer.

Her invention has restored sight to people worldwide. A fierce advocate for equitable healthcare access, Dr. Bath co-founded the American Institute for the Prevention of Blindness, championing the idea that eyesight is a human right.

Jeanne Villepreux-Power: Mother of Marine Biology

In the 1830s, French naturalist Jeanne Villepreux-Power invented the aquarium and changed marine science forever. Her portable, controlled-environment design allowed scientists to study marine life up close, outside the ocean, opening new possibilities for discovery and conservation.

Before her invention, studying aquatic animals meant entirely removing them from their environment. Thanks to Villepreux-Power, marine biology grew into a field of deep exploration and understanding.

She was among the first to challenge the belief that female scientists couldn’t contribute to rigorous natural science, proving through invention that knowledge knows no gender.

Invention is about new tools and technologies, access, and the exponential value of diverse experiences.

This National Inventors Month, we uplift the legacies of Maria Telkes, Dr. Patricia Bath, and Jeanne Villepreux-Power for what they built and made possible. The future of STEM is bold and inclusive.
