Katherine Johnson vs Rosalind Franklin
Yes — based on their recorded years, Katherine Johnson (1918–2020) and Rosalind Franklin (1920–1958) were alive at the same time for at least part of their lives.
Katherine Johnson
Katherine Johnson was an American mathematician whose calculations were critical to NASA's early human spaceflight missions, including John Glenn's 1962 orbital flight.
Key achievements
- Joined NASA's precursor agency, NACA, in 1953 as a 'human computer.'
- Calculated the trajectory for Alan Shepard's 1961 spaceflight, the first American in space.
- Verified the orbital trajectory calculations for John Glenn's historic 1962 orbital flight.
- Received the Presidential Medal of Freedom in 2015 for her contributions to space exploration.
Fast fact
Johnson's story, along with those of fellow Black NASA mathematicians Dorothy Vaughan and Mary Jackson, was popularized decades later in the book and film 'Hidden Figures,' bringing overdue recognition to their contributions.
Full profile of Katherine Johnson →Rosalind Franklin
Rosalind Franklin was a British X-ray crystallographer whose imaging work was crucial to discovering the double-helix structure of DNA, though her contribution was long underrecognized.
Key achievements
- Produced the landmark X-ray diffraction image known as 'Photo 51' in 1952.
- Provided crucial data supporting the discovery of DNA's double-helix structure.
- Conducted pioneering research on the molecular structure of viruses later in her career.
- Was posthumously recognized for her critical scientific contributions after decades of being overlooked.
Fast fact
Franklin's famous 'Photo 51,' an X-ray diffraction image she produced in 1952, provided critical evidence of DNA's helical structure, but she died in 1958 before Watson and Crick received the Nobel Prize partly built on her data.
