Gladys West (born October 27, 1930, Sutherland, Virginia) American mathematician known for her work contributing to the development of the Global Positioning System (GPS). But at school her talent for learning offered another path. As valedictorian of her high-school graduating class, Gladys received a full scholarship to Virginia State College (now Virginia State University), the historically Black college where she earned a degree in mathematics in 1952. She later returned for a master’s degree in the subject, graduating in 1955—after spending time teaching math in racially segregated Virginia schools. In 1956 Gladys was hired as a mathematician by the U.S. Naval Proving Ground, a weapons laboratory in Dahlgren, Virginia, as only their fourth Black employee. There she met Ira V. West, another Black mathematician on the base; the couple married in 1957 and had three children. At Dahlgren, Gladys West was admired for her ability to solve complex mathematical equations by hand. She eventually transitioned from solving those equations herself to programming computers to do it for her.  In 1978 West was named project manager of Seasat, an experimental U.S. ocean surveillance satellite designed to provide data on a wide array of oceanographic conditions and features, including wave height, water temperature, currents, winds, icebergs, and coastal characteristics. It was the first project to demonstrate that satellites could be used to observe useful oceanographic data. Out of West’s work on Seasat came GEOSAT, a satellite programmed to create computer models of Earth’s surface. By teaching a computer to account for gravity, tides, and other forces that act on Earth’s surface, West and her team created a program that could precisely calculate the orbits of satellites. These calculations made it possible to determine a model for the exact shape of Earth, called a geoid. It is this model, and later updates that allows the GPS system to make accurate calculations of any place on earth. During her career on the naval base, West earned another master’s degree in 1973, this time in public administration from the University of Oklahoma. Though she retired from the base in 1998 at age 68, she continued her education: after recovering from a stroke, she received a Ph.D. in public administration and policy affairs from Virginia Polytechnic Institute in 2000 at age 70. Like NASA mathematicians Katherine Johnson, Dorothy Vaughan, and Mary Jackson, West is often called one of history’s “hidden figures”: individuals, often Black women, whose insightful contributions to science went unrecognized in their time because of their race or gender. In 2018 West was formally recognized for her contribution to the development of GPS by the Virginia General Assembly. That same year she was also inducted into the Air Force Space and Missile Pioneers Hall of Fame and named one of the British Broadcasting Corporation’s 100 Women of 2018, a list designed to honor inspiring women worldwide
