The Genius of Black People
Created by Rev. Dr. Otis Moss III, TheHub.news presents its Black History Month series celebrating the genius of Black people—stories of courage, faith and creativity forged in struggle. Inspired by ancestors like Walter Francis White, this series honors sacred memory and lifts up the divine brilliance shaping justice and resilience today.
For decades, the precision of modern navigation has quietly rested on the work of Dr. Gladys West (October 27, 1930–January 13, 2026), a mathematician whose brilliance helped shape the Global Positioning System (GPS). Her story is one of mathematical genius applied with persistence, rigor and remarkable foresight.
Raised by farmers in Dinwiddie County, Virginia, just south of Richmond, West recounts her early aspirations in her memoir It Began with a Dream. As a student in a one-room schoolhouse, she imagined escaping the strenuous, never-ending labor of farm life through education. Recognizing early that academic excellence was her path forward, she worked diligently to become valedictorian of her class, earning a scholarship to Virginia State College. There, her exceptional ability in mathematics quickly became evident.
In 1956, West was hired as a mathematician at the U.S. Naval Proving Ground in Dahlgren, Virginia, where she was one of only a few Black employees and even fewer women. She specialized in complex mathematical modeling and computer programming, initially working on ballistic missile trajectories. Long before the term “data science” existed, her strength lay in translating the irregular realities of the physical world into precise mathematical relationships and executable code.
Her most groundbreaking work emerged when she turned her attention to the shape of the Earth itself. The planet is not a perfect sphere but an irregular, dynamic body known as the geoid. To determine any position accurately, that shape must be modeled with extraordinary precision. West led and contributed to projects that used satellite data to calculate subtle variations in gravity, sea level, rotation and Earth’s dimensions. Through years of meticulous computation and algorithm development, she helped establish the mathematical foundation that allows GPS satellites to pinpoint locations within meters, and in some cases, centimeters.
Working during a period when racism and sexism sharply limited opportunities, West pursued mathematics not as an abstract passion but as a powerful tool for understanding and shaping the world. Her work ensured that corrections for Earth’s shape, rotation and gravitational field were embedded at the core of GPS technology. Every navigation app, aircraft guidance system and precision-mapping tool relies, in part, on the accuracy of her models.
Dr. West’s genius lies not only in the elegance of her mathematics but in her unwavering commitment to accuracy and methodical problem-solving under both technological and social constraints. Although her role was widely recognized only in recent years, her impact has been global for decades. Each time a device guides a traveler safely to their destination, it stands as a quiet testament to the mathematical brilliance of Gladys West.
