Why did Rosalind Franklin want to be a scientist?
Rosalind Franklin was extremely intelligent and she knew by the age of 15 that she wanted to be a scientist. Her father actively discouraged her interest since it was very difficult for women to have such a career.
What did Rosalind Franklin do with the structure of DNA?
When water was extracted from this fibre, its structure showed orderly, repetitive, quasi-crystalline properties. Rosalind Franklin developed methods of adding water to A-form DNA. With the help of her X-ray diagrams, Franklin was able to show that the structure of the DNA had changed after the water was removed.

Early Life
Studies
- Rosalind Franklin developed her interest in science at school, and by age 15 she decided to become a chemist. She had to overcome the opposition of her father, who did not want her to attend college or become a scientist; he preferred that she go into social work. She earned her Ph.D. in chemistry in 1945 at Cambridge. After graduating, Rosalind Franklin stayed and worked …

But it was not until the middle of the 20th century when scientific met...
Cancer
- In 1956, Franklin discovered she had tumors in her abdomen. She continued to work while undergoing treatment for cancer. She was hospitalized at the end of 1957, returned to work in early 1958, but soon became unable to work. She died in April. Rosalind Franklin did not marry or have children; she conceived of her choice to go into science as giving up marriage and children.
Legacy
- Watson, Crick, and Wilkins were awarded the Nobel Prize in physiology and medicine in 1962, four years after Franklin died. The Nobel Prize rules limit the number of people for an award to three and also limit the award to those who are still alive, so Franklin was not eligible for the Nobel. Nevertheless, many have thought that she deserved explicit mention in the award and that her k…
