Rosalind Franklin: The Unsung Hero of DNA Structure Discovery

The discovery of the structure of DNA is one of the most important scientific breakthroughs of the 20th century. It was a collaborative effort between several scientists, but one of the most important contributors was Rosalind Franklin. Despite her critical role in the discovery, she has often been overlooked and her contributions have been overshadowed by those of her male colleagues.

Early Life and Education

Rosalind Franklin was born in London in 1920. She was the second of five children and the only daughter of Ellis and Muriel Franklin. Her father was a successful businessman and her mother was a civil servant. She was a bright and inquisitive child who excelled in her studies. She attended the prestigious St. Paul’s Girls’ School in London and went on to study chemistry at Newnham College, Cambridge.

Career in Science

Franklin went on to pursue a career in science, specializing in X-ray crystallography. This technique uses X-rays to study the structure of molecules. She worked at the British Coal Utilization Research Association, where she studied the structure of coal and other carbon-based molecules. In 1951, she moved to King’s College London, where she began to study the structure of DNA.

The Discovery of DNA’s Structure

At King’s College, Franklin worked with Maurice Wilkins and Raymond Gosling to study the structure of DNA. She used X-ray crystallography to take detailed photographs of DNA fibers. Her photographs revealed the helical structure of DNA, which was the key to unlocking its secrets.

Franklin’s work was critical to the discovery of DNA’s structure, but her male colleagues often took credit for her work. Wilkins and James Watson, who worked at the University of Cambridge, used Franklin’s data without her knowledge or permission. Watson and Francis Crick then used this data to build a model of DNA’s structure.

Legacy

Despite her critical role in the discovery of DNA’s structure, Franklin’s contributions were often overlooked. She died in 1958 at the age of 37, before the Nobel Prize was awarded to Watson, Crick, and Wilkins in 1962.

Franklin’s legacy is now being recognized and celebrated. She is remembered as a pioneering scientist who made significant contributions to the field of genetics. Her work paved the way for further discoveries in the field of molecular biology and genetics.
