Dr. Gladys West's mathematical modeling of Earth's shape was one of the scientific breakthroughs that made modern GPS accuracy possible. She grew up on a farm in Sutherland in Dinwiddie County, Virginia, and her family made a living working long hours in the fields. She said she didn’t want a life "being out in the sun." So Dr. West worked hard, made good grades in all of her classes, and graduated valedictorian of her high school in 1948. She received a scholarship to study mathematics at Virginia State University, and her love of learning carried her all the way to a job as a mathematician at a U.S. Navy base in Dahlgren, Virginia.
GPS was not invented by a single person. It was developed over many decades through the work of many engineers and scientists within the U.S. Department of Defense. In the 1950s and 1960s, early computers began arriving in military labs, universities, and research centers. Mathematicians like Dr. West had to learn programming as they moved from traditional paper-and-pencil calculations to digital systems. Her quiet and careful work became the hidden engine inside every map on every phone.
Now, billions of people depend on GPS every day through apps like Google Maps, Apple Maps, and Uber. And many don't even think twice about it. Dr. West's work quietly supports the flights we board and the routes that guide us home. Her contribution did more than strengthen GPS. It changed the way the entire world finds its way. Dr. West wrote about her story in her 2020 book "It Began with a Dream." She is 95 years old, a mother and a wife, and for decades she was a "hidden figure." But now the world knows her name.
