Rosalind Franklin

Rosalind Elsie Franklin was a born 25 July 1920 in London. Franklin went to Newnham College, Cambridge in 1938 and studied chemistry.

She was a British scientist (chemist and X-ray crystallographer) whose work was key to understanding the structure of DNA (deoxyribonucleic acid).

Photograph 51

In May 1952 at King's College London, she and her assistant Raymond Gosling took Photograph 51 - an X-ray diffraction image that showed the double helix structure of DNA.

The image was tagged "photo 51" because it was the 51st diffraction photograph that Franklin and Gosling had taken.

The discovery of DNA

James Watson and Francis Crick built upon Rosalind Franklin's findings in their research which lead to the discovery of the molecular structure of DNA.

Watson, Crick and Maurice Wilkins shared the Nobel Prize in Medicine in 1962. Rosalind Franklin died of cancer in 1958 at the age of 37, as the prize was not awarded posthumously, Franklin was not recognised at this time for her important, perhaps critical contribution.

Whilst it is generally agreed that Photo 51 played an important role in the discovery of DNA, 1 year before Photo 51 was captured, another British scientist William Astbury and his research assistant Elwyn Beighton took a striking similar x-ray image.

Rosalind Franklin 50p

This coin is the second release in the Royal Mint's Innovation in Science series that began in 2019 with the Stephen Hawking 50p.

Release date is expected to be this year, but the exact date is unknown. 2020 marks the 100th anniversary of the birth of Rosalind Franklin on the 25th of July 1920.
