When we think about STEM — science, technology, engineering, and mathematics — we often picture famous figures like Albert Einstein, Marie Curie, or Isaac Newton. But behind many everyday technologies and life-changing discoveries are brilliant innovators of color whose names often don’t make it into textbooks. Their creativity, persistence, and problem-solving have shaped our modern world in powerful ways.
Dr. Gladys West — The Hidden Genius Behind GPS
Before smartphones could tell us how to get from one place to another, Dr. Gladys West, an African American mathematician, was hard at work developing the complex mathematical models that made Global Positioning Systems (GPS) possible.
Working for the U.S. Navy in the 1950s and 60s, Dr. West used her math skills to create computer programs that mapped the shape of the Earth with incredible precision. Her work laid the foundation for the GPS technology we use today in phones, cars, and even space exploration.
Dr. Ellen Ochoa — Breaking Barriers in Space and Science
As the first Hispanic woman in space, Dr. Ellen Ochoa not only made history as an astronaut but also contributed to optical engineering — designing systems that allow computers and satellites to process light and images more effectively.
Her innovations have improved how telescopes and satellites capture data, helping scientists learn more about Earth and the universe. Later, she became the Director of NASA’s Johnson Space Center, inspiring countless young people to reach for the stars — literally.
Dr. Percy Julian — Turning Chemistry into Hope
Dr. Percy Julian, an African American chemist, overcame racial barriers in the early 1900s to become one of the most influential chemists in history. He developed affordable ways to produce medicines from plants, including synthetic cortisone and steroids used to treat arthritis and allergies.
His work made vital treatments more accessible and affordable, proving that science can transform lives when guided by purpose and innovation.
Dr. Mark Dean — The Technology Behind Your Computer
Every time you use a computer, you’re benefiting from the work of Dr. Mark Dean, an African American computer scientist and engineer who helped design the IBM personal computer in the 1980s. He co-created the ISA bus system, a technology that allows computers to connect with printers, modems, and other devices — a crucial step in the evolution of modern computing.
Dr. Dean also holds three of IBM’s original nine PC patents, reminding us that innovation comes from diverse thinkers who shape how we live and work.
Why These Innovators Matter
Each of these scientists, engineers, and inventors faced challenges — from racial discrimination to lack of recognition — yet their contributions changed the world. Their stories remind us that STEM belongs to everyone, and that creativity and determination can break through any barrier.
When students see themselves represented in science and innovation, they realize that their ideas, too, can spark the next breakthrough — in medicine, technology, space exploration, or beyond.
