Dorothy Jean Johnson Vaughan (September 20, 1910 – November 10, 2008) was an American
mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems.
Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change.

Hampton, Virginia. In 1949, she became acting supervisor of the
West Area Computers, the first African-American woman to receive a promotion and supervise a group of staff at the center.
She later was promoted officially to the position of supervisor. During her 28-year career, Vaughan prepared for the introduction of computers in the early 1960s by teaching herself and her staff the programming language of
Fortran. She later headed the programming section of the Analysis and Computation Division (ACD) at Langley.

Early life
Vaughan was born September 20, 1910, in
Kansas City, Missouri, as Dorothy Jean Johnson.
She was the daughter of
Annie and Leonard Johnson. At the age of seven, her family moved to
Morgantown, West Virginia, where she graduated from Beechurst High School in 1925 as her class

In 1932, she married Howard Vaughan, who died in 1955. The couple moved to
Newport News, Virginia, where they had six children: Ann, Maida, Leonard, Kenneth, Michael and Donald.
The family also lived with Howard's wealthy and respected parents and grandparents on South Main Street in Newport News, Virginia. Vaughan was very devoted to family and the church, which would play a huge factor in whether she would move to Hampton, Virginia, to work for NASA.

Executive Order 9346 to end racial segregation and discrimination in hiring and promotion among federal agencies and defense contractors.
These helped ensure the war effort drew from all of American society after the United States entered World War II in 1942. With the enactment of the two Executive Orders, and with many men being swept into service, federal agencies such as the
National Advisory Committee for Aeronautics

(NACA) also expanded their hiring and increased recruiting of women, including women of color, to support the war production of airplanes.
Two years following the issuance of Executive Orders 8802 and 9346, the Langley Memorial Aeronautical Laboratory (Langley Research Center), a facility of the NACA, began hiring more black women to meet the drastic increase in demand for processing aeronautical research data.
The US believed that the war was going to be won in the air. It had already ramped up airplane production, creating a great demand for engineers, mathematicians, craftsmen and skilled tradesmen.
In 1943, Vaughan began a 28-year-career as a mathematician and programmer at
Langley Research Center in
Hampton, Virginia, in which she specialized in calculations for

. Her career in this field kicked off during the height of World War II. She came to the Langley Memorial Aeronautical Laboratory thinking that it would be a temporary war job. One of her children later worked at NACA.
Vaughan was assigned to the
West Area Computing, a segregated unit, which consisted of only African Americans. This was due to prevailing Jim Crow laws that required newly hired African American women to work separately from their white women counterparts.
They were also required to use separate dining and bathroom facilities.
This segregated group consisted of African-American women who made complex mathematical calculations by hand, using tools of the time.
The West Computers made contributions to every area of research at Langley. Their work expanded in the postwar years to support research and design for the United States' space program, which was emphasized under President

. In 1949, Vaughan was assigned as the acting head of the
West Area Computers, taking over from a white woman who had died. She was the first black supervisor at NACA and one of few female supervisors. She led a group composed entirely of African-American women mathematicians.
She served for years in an acting role before being promoted officially to the position as supervisor. Vaughan worked for opportunities for the women in West Computing as well as women in other departments.
Seeing that machine computers were going to be the future, she taught the women programming languages and other concepts to prepare them for the transition. Mathematician

was initially assigned to Vaughan's group, before being transferred to Langley's Flight Mechanics Division. Vaughan moved into the area of electronic computing in 1961, after NACA introduced the first
digital (non-human) computers to the center. Vaughan became proficient in computer programming, teaching herself
FORTRAN and teaching it to her coworkers to prepare them for the transition. She contributed to the space program through her work on the
Scout Launch Vehicle Program.

felt like being on "the cutting edge of something very exciting". Regarding being an African American woman during that time in Langley, she remarked, "I changed what I could, and what I couldn't, I endured." Vaughan worked in the Numerical Techniques division through the 1960s. Dorothy Vaughan and many of the former West Computers joined the new Analysis and Computation Division (ACD), a racially and gender-integrated group on the frontier of electronic computing. She worked at NASA-Langley for 28 years.
During her career at Langley, Vaughan was also raising her six children. One of them later also worked at NASA-Langley. Vaughan lived in
Newport News, Virginia, and commuted to work at Hampton via public transportation.
