Early Life and Education
Rosalind Franklin, born in 1920, was the second of five children to a prominent British Jewish family. She grew up in a family that encouraged intellectual curiosity and debate. Her father, Ellis Franklin, was a prominent industrialist who co-owned a plant for manufacturing electrical equipment. (1)
Franklin attended St. Paul’s Girls’ School in London, where she excelled academically, especially in science. Her chemistry teacher, Maud Menten, a renowned biochemist, recognized her potential and provided her with extra guidance and resources. (2)
After completing her education at St. Paul’s, Franklin was awarded a scholarship to study natural sciences at Newnham College, Cambridge, in 1938. She graduated from Cambridge with a second-class degree in 1941. In 1942, she began her Ph.D. studies at the University of Cambridge under the guidance of Ronald George Wreyford Norrish, a Nobel laureate in chemistry. (3)
It was during her Ph.D. studies that she developed an interest in X-ray crystallography, the scientific technique that she would become renowned for. Her work on coal provided the foundation for her future work in crystallography. (4)

The Race for DNA’s Structure
During the mid-20th century, a race to unravel the structure of DNA took hold of the scientific community. Early efforts were marred by skepticism and controversy, but Rosalind Franklin’s X-ray crystallization techniques provided groundbreaking data on the elusive molecule.
Franklin’s methodology produced Photo 51, an X-ray diffraction image that proved critical in the discovery of DNA’s unique double helix structure. Despite her essential contributions, Franklin was left out of the Nobel Prize awarded to Watson, Crick, and Wilkins for the discovery.
The intense race for DNA’s structure helped propel molecular biology into a modern age of research. Franklin’s crucial work continues to influence our understanding of DNA’s fundamental role in human biology and disease.
Franklin’s X-ray Crystallography
Rosalind Franklin’s utilization of X-ray crystallography revolutionized the field of DNA research and paved the way for future discoveries in molecular biology. Despite the challenges she faced, such as creating high-quality images with limited technology and unstable samples, Franklin’s persistence and skill allowed her to produce remarkable images that provided key insights into DNA’s structure.
The most iconic of these images, known as Photo 51, was captured by Franklin in 1952 and showcased the helical nature of DNA. Its significance was later recognized by James Watson and Francis Crick, who used her data as a basis for their double helix model of DNA, leading to their Nobel Prize win in 1962.
This breakthrough method of using X-ray diffraction to study the properties of molecules continues to be an essential tool in modern scientific research, and Rosalind Franklin’s pioneering work in this area is a testament to her innovative spirit and immense contributions to the field of molecular biology.
Photo 51 and the Double Helix
One of Rosalind Franklin’s most significant contributions to science is the iconic Photo 51, an X-ray diffraction image that provided crucial evidence for the double helix structure of DNA. In 1952, Franklin and her colleague, Maurice Wilkins, captured Photo 51 as part of their research at King’s College London. The image revealed a distinct “X” shape that indicated the helical structure of DNA.
The significance of Photo 51 was not immediately recognized until James Watson and Francis Crick, who were also racing to discover DNA’s structure, saw the image in 1953. They famously used the information from Photo 51, which had been shared without Franklin’s knowledge or consent, to construct their own model for the double helix.
Despite this controversy, Franklin’s contribution to the discovery of the double helix remains undeniable. Photo 51 provided vital evidence for the helical structure of DNA and informed the subsequent research in the field. It also highlighted the importance of recognizing and respecting the work of all scientists, regardless of gender or background.
Contributions to Science and Research
Beyond her groundbreaking work on DNA, Rosalind Franklin made significant contributions to multiple fields of science. Her dedication to research and her meticulous attention to detail produced important discoveries and advancements in various disciplines.
Carbon Fibers
In 1952, Franklin began exploring the structure of carbon fibers, leading to her discovery of the different planes of atoms within the material. Her research paved the way for further study of the structure and properties of carbon fibers, which are widely used today in a variety of industries.
Virus Structure
Franklin’s expertise in X-ray crystallography also led to her groundbreaking work in studying the structure of viruses. Her research on the tobacco mosaic virus in the early 1950s was instrumental in understanding the basic mechanism of viral infection and replication, informing the development of treatments for viral diseases.

Franklin’s work on DNA and beyond had a lasting impact on numerous scientific disciplines, earning her the respect and admiration of her colleagues and future generations of researchers.
The Controversy and Legacy
Despite Rosalind Franklin’s significant contributions to the discovery of DNA’s structure, controversy surrounded her role and subsequent recognition. Franklin’s crucial DNA research and X-ray crystallography provided crucial evidence for the double helix structure of DNA. However, her male colleagues, James Watson and Francis Crick, famously used her data without permission in their discovery of DNA’s structure, leading to questions about Franklin’s contribution and recognition in the scientific community.
“The data were really clear-cut…The helix was right-handed, and the phosphate groups stuck out to the right…It was too pretty to be wrong.” – Rosalind Franklin
Furthermore, issues of gender discrimination and unequal opportunities for women in scientific fields of research plagued Franklin’s experiences. Despite these challenges, Franklin’s legacy remains intact as an important figure in the history of molecular biology, and her work continues to shape scientific inquiry and inspire women in scientific fields.
