Gladys West

Gladys West was a brilliant mathematician who helped change how we find our way.

She used math to study the shape of our planet. Most people think the Earth is a perfect round ball. However, the Earth has bumps and dips caused by gravity and tides. Gladys worked to create models that showed this true shape. This shape is called a geoid. Her work on these models helped make the Global Positioning System, or GPS, possible. This system uses satellites to tell us exactly where we are on Earth.

To do this hard job, Gladys had to work with huge amounts of data. In the early 1960s, she helped with a study about the planets Pluto and Neptune. This project used a massive computer and required five billion calculations. She used punched cards to feed information into the machines. Later, she worked with satellite data to map the Earth's surface. She even managed a project called Seasat. This was the first satellite that could sense the oceans from space. Her clever ways of working cut the time needed to process data in half.

Gladys grew up in a rural part of Virginia.

Her family were farmers and sharecroppers. She saw education as a way to build a different life. In 1948, she graduated at the top of her high school class. This earned her a scholarship to Virginia State University. She studied mathematics, even though most students were men. She earned her Bachelor of Science in 1952. She also earned a Master of Mathematics in 1955. Later, she finished a PhD in Public Administration at Virginia Tech.

In 1956, Gladys began working at the Naval Proving Ground in Dahlgren, Virginia.

She was one of only four Black employees at the base. She worked there for 42 years until she retired in 1998. During her career, she faced many hardships because of racism. She often did not get the same praise as her white coworkers. Much of her important work was kept secret for a long time. Even her own children did not know how much she helped create GPS. She preferred using paper maps because she liked to see the roads with her own eyes.

Many people now celebrate the amazing things Gladys achieved. In 2018, she was put into the United States Air Force Hall of Fame. She also received the Webby Lifetime Achievement Award. The Royal Academy of Engineering gave her the Prince Philip Medal in 2021. In 2024, a school in Fredericksburg, Virginia, was named Gladys West Elementary School. Her life shows how math can help us understand the whole world. She was a true pioneer in the field of science.
