Dorothy Johnson was born in Kansas City, Missouri on September 20, 1910. She graduated from Beechurst High School in 1925, and four years later, received a Bachelor of Science degree from Wilberforce University in Ohio. In 1932, she married Howard Vaughan. For the next eleven years, Vaughan divided her time between being a homemaker and a mathematics teacher at Robert Russa Moton High School in Farmville, Virginia. In 1943, the family moved to Newport News, Virginia, and Vaughan was employed as a mathematician at the National Advisory Committee for Aeronautics in what she thought would be a temporary job. She was assigned to the segregated "West Area Computing" unit. In 1949, Vaughan became the first Black supervisor at NACA when she was promoted to manager of the West Area Computers. In 1958, as NACA was transitioning into the National Aeronautics and Space Administration (NASA), the agency abolished the segregated working environment. Vaughan joined the new Analysis and Computation Division, becoming an expert FORTRAN programmer, and worked on the SCOUT (Solid Controlled Orbital Utility Test) Launch Vehicle Program, one of the nation's most successful and reliable launch vehicles, used for launching a 385-pound satellite into a 500-mile orbit.Vaughan sought but never received another management position at NASA. She retired in 1971. During the final decade of her career, Vaughan worked closely with fellow NASA mathematicians Katherine G. Johnson and Mary Jackson on the launch of astronaut John Glenn into orbit, which brought confidence back to America's space program. Vaughan died on November 10, 2008.
