Katherine Johnson death date and key facts
Katherine Johnson, the NASA mathematician whose calculations were critical for early U.S. human spaceflight, died on February 24, 2020. She was 101 years old at her time of death. Johnson passed away at a care facility in Newport News, Virginia, where she had lived in recent years. Her death was widely reported by NASA, national news outlets, and the U.S. space community, marking the end of a life that exemplified precise mathematics, persistence, and barrier-breaking contributions to aerospace. This verified explainer clarifies the timeline, context, and legacy of her work.
Why the date is verified and how we know it
Official sources including NASA’s news release, family statements, and contemporaneous news coverage from February 2020 confirm the date. The combination of public obituaries, institutional records, and multiple reputable media reports establishes high confidence in February 24, 2020 as the date of death. Cross-referencing these sources reduces uncertainty and supports a fact-first conclusion.
Biographical context and career highlights
Born on August 26, 1918, in White Sulphur Springs, West Virginia, Katherine Johnson excelled in mathematics and taught before joining NASA in the 1950s. At NASA, she calculated trajectories for Alan Shepard’s Mercury mission and John Glenn’s orbital flight, and contributed to Apollo’s lunar landing trajectory. Her technical rigor and advocacy for accuracy became legendary. She received the Presidential Medal of Freedom in 2015 and remained a widely recognized public figure until her death.
