Dr. Gladys West, the brilliant mathematician whose groundbreaking work helped turn raw satellite data into the GPS technology billions rely on daily, has died at 95.
Born in Jim Crow-era Virginia, Dr. West overcame systemic racial and gender barriers to excel academically, graduating valedictorian and earning advanced math degrees. Her pioneering career at the U.S. Naval Surface Warfare Center as one of its earliest Black female mathematicians revolutionized satellite geodesy.
Through meticulous calculations and early computer programming, she created precise Earth models that became the backbone of modern GPS systems—enabling everything from smartphone navigation to global air travel.
Dr. West’s quiet genius and perseverance not only broke barriers but forged a new era in technology. Her legacy guides us every time we find our way on land, sea, or sky.
She is remembered and honored as a true STEM pioneer. Rest in power, Dr. Gladys West.
