Rosalind Franklin
Rosalind Franklin was a British scientist whose X-ray diffraction work made crucial contributions to understanding the molecular structures of DNA and viruses.
Rosalind Franklin was a British scientist whose X-ray diffraction work made crucial contributions to understanding the molecular structures of DNA and viruses. She is best known for helping establish that DNA has a helical structure, and her research also advanced structural virology and studies of carbon materials. She died in 1958 at age 37.
Early life and education
Rosalind Franklin was born in London in 1920 and later studied at Cambridge. She trained in physical chemistry and developed expertise in crystallography and X-ray diffraction.
DNA research at King's College London
At King's College London, Franklin used X-ray diffraction to investigate DNA structure. Her measurements and images provided critical evidence for the helical nature of DNA and the presence of distinct molecular forms.
Later work on viruses and carbon
After leaving King's College, Franklin moved to Birkbeck College, where she studied virus structures. She also made contributions to research on coal and graphite.
Legacy
Franklin is widely recognized as a major contributor to modern molecular biology and structural virology. Her scientific reputation grew substantially after her death, and she became an important figure in discussions of women in science.
Key facts
- Franklin used X-ray diffraction to study the structure of DNA and other biological materials.
- Her work helped show that DNA exists in a helical form and distinguish between two DNA forms, A and B.
- She produced the famous DNA image often referred to as Photograph 51, associated with the B form of DNA.
- After King's College London, she researched virus structures at Birkbeck College.
- Her broader scientific work included important studies of coal, graphite, and viruses.
Franklin’s work is part of the global scientific history taught in Canadian schools and universities, especially in biology, chemistry, and the history of women in science.
