As we celebrate Black History Month, we honor Valerie Thomas, an African American scientist and inventor whose groundbreaking work at NASA changed the way we view and transmit images.
Born on February 8, 1943, in Baltimore, Maryland, Thomas overcame racial and gender barriers to become a leading figure in space science and technology.
Breaking Barriers in STEM
From an early age, Thomas was fascinated by electronics, mathematics, and physics—fields where women, particularly Black women, were often discouraged.
Despite these challenges, she excelled in school and later earned a bachelor’s degree in physics from Morgan State University in 1964. She then joined NASA as a data analyst, working on satellite missions that helped scientists study Earth and space.
Inventing the Future of 3D Technology
In 1976, a simple optical illusion inspired Thomas to develop her most famous invention: the illusion transmitter. This revolutionary device, patented in 1980, transmits three-dimensional images that appear to float in space.
NASA later incorporated her technology into satellite applications, and today, it serves as the foundation for advancements in holography, medical imaging, and even television screens.
Advancing Space Science and Inspiring Future Generations
Throughout her career, Thomas made significant contributions to satellite imaging and data processing. She helped develop NASA’s Landsat program, which monitors Earth’s natural resources using infrared and satellite technology.
As a leader in space science, she managed projects like the Space Physics Analysis Network, which connected scientists worldwide.
Thomas retired from NASA in 1995 but remained a dedicated advocate for STEM education, particularly for African American students and young girls. She actively participated in organizations like Women in Science and Engineering (WISE) and Shades of Blue, encouraging the next generation to pursue careers in science, technology, engineering, and mathematics.
Her legacy continues to shine as a symbol of Black excellence in STEM.
