Annie Easley


Annie J. Easley was an American computer scientist, mathematician, and rocket scientist. She worked for the Lewis Research Center of the National Aeronautics and Space Administration and its predecessor, the National Advisory Committee for Aeronautics. She was a leading member of the team which developed software for the Centaur rocket stage, and was one of the first African-Americans to work as a computer scientist at NASA.

Early life and education

Annie Easley was born to Samuel Bird Easley and Mary Melvina Hoover in Birmingham, Alabama. Before the Civil Rights Movement, educational and career opportunities for African-American children were very limited. African-American children were educated separately from white children, and their schools were often inferior to white schools. Annie's mother told her that she could be anything she wanted but she would have to work at it. She encouraged Annie to get a good education. From the fifth grade through high school, Annie attended Holy Family High School, and was valedictorian of her graduating class.
In 1950, Easley enrolled in classes at Xavier University in New Orleans, which was then an African-American Roman Catholic University, and majored in pharmacy for about two years.
In 1954, she returned to Birmingham. As part of the Jim Crow laws that maintained racial inequality, African Americans were required to pass a literacy test and pay a poll tax in order to vote, which was outlawed in 1964 in the Twenty-fourth Amendment. She remembered the test giver looking at her application and saying only, "You went to Xavier University. Two dollars." Subsequently, she helped other African-Americans prepare for the test.
Shortly thereafter, she moved to Cleveland to be closer to her husband's family, with the intention of continuing her studies. Unfortunately, the local university had ended its pharmacy program a short time before and no nearby alternative existed.
Throughout the 1970s, Easley advocated for and encouraged female and minority students at college career days to work in STEM careers.

Career at NACA and NASA

In 1955, she read a story in a local newspaper about twin sisters who worked for the National Advisory Committee for Aeronautics as "computers". She applied for a job the next day, and was hired two weeks later - one of four African Americans of about 2500 employees. She began her career as a mathematician and computer engineer at the NACA Lewis Flight Propulsion Laboratory in Cleveland, Ohio. She continued her education while working for the agency, and in 1977, obtained a Bachelor of Science in Mathematics from Cleveland State University. As part of a continuing education, Easley worked through specialization courses offered by NASA. Easley was denied financial aid that other employees received for education, without explanation from the agency.
Her 34-year career included developing and implementing computer code that analyzed alternative power technologies, supported the Centaur high-energy upper rocket stage, determined solar, wind and energy projects, identified energy conversion systems and alternative systems to solve energy problems. Her energy assignments included studies to determine the life use of storage batteries, such as those used in electric utility vehicles. Her computer applications have been used to identify energy conversion systems that offer the improvement over commercially available technologies. She retired in 1989. Despite her long career and numerous contributions to research, she was cut out of NASA's promotional photos.
Easley's work with the Centaur project helped lay the technological foundations for future space shuttle launches and launches of communication, military and weather satellites. Her work contributed to the 1997 flight to Saturn of the Cassini probe, the launcher of which had the Centaur as its upper stage.
Annie Easley was interviewed in Cleveland on August 21, 2001 by Sandra Johnson. The interview is stored in the National Aeronautics and Space Administration Johnson Space Center Oral History Program. The 55 page interview transcript includes material on the history of the Civil Rights Movement, Glenn Research Center, Johnson Space Center, space flight, and the contribution of women to space flight.
