West was born in 1930 in Virginia. Despite the oppression of Jim Crow laws in the south, she was able to pursue higher education at Virginia State College (now named Virginia State University), obtaining bachelor's and master's degrees in mathematics. In 1956, West was hired at what is now called the Naval Surface Warfare Center in Dahlgren, VA. Her focus during the 1970s and 1980s was creating accurate models of the Earth's shape based on satellite data, a complex task requiring the type of mathematical gymnastics that would make the average person dizzy. Those models later became the backbone for GPS. West worked at the Dahlgren center for 42 years, retiring in 1998.

As has been the case with so many of the women, particularly those of color, behind tech and science breakthroughs in the US, West's work went largely uncelebrated for decades. After submitting a short biography of her accomplishments to a sorority function in 2018, members of Alpha Kappa Alpha helped West to receive belated recognition for her contributions. She was inducted into the US Air Force Space and Missiles Pioneers Hall of Fame and honored as Female Alumna of the Year by the Historically Black Colleges and Universities Awards in that same year. The Guardian published an interview with West in 2020 that shared some insights on her journey, including a note that when West was out and about, she favored paper maps over the technology she indirectly helped create.
