In today’s moment in Black History, we will highlight Dr. Gladys Mae West (October 27, 1930 – January 17, 2026), the mathematician whose precise calculations helped give the world GPS.
Born to sharecropper parents in rural Sutherland, Virginia, Gladys saw education as her way forward. She excelled in a one-room segregated schoolhouse, graduated as valedictorian, and won a full scholarship to Virginia State College, where she earned her degree in mathematics.
In 1956 she joined the Naval Surface Warfare Center Dahlgren Division…becoming one of the very few Black women scientists there in an era when the workplace remained largely segregated and dominated by white males. Undeterred, she applied her skill to massive data sets and early computers, modeling the Earth’s irregular shape, gravitational variations, and ocean surfaces with extraordinary accuracy. Those models became essential building blocks for satellite-based navigation systems.
Fun fact: Much of her foundational work relied on hand calculations and punch-card programming long before personal computers existed…she literally helped measure the planet by hand and machine.
She later earned her doctorate from Virginia Tech at age 70, raised a family with her husband Ira (also a mathematician), and continued contributing for decades. Recognition came later in life; in 2018 she was inducted into the Air Force Hall of Fame for her role in GPS development.
Dr. West’s quiet persistence turned overlooked talent into global infrastructure we use every day. Her story shows what becomes possible when barriers are met with determination.
Remember…Education is freedom of mind and never should be colorblind.
