Rosalind Franklin: A Brilliant Mind in Science

Have you ever been amazed by scientific breakthroughs? Throughout history, there have been many brilliant minds that have made significant discoveries, from Albert Einstein to Marie Curie. Today, we will explore the life and achievements of one such remarkable scientist – Rosalind Franklin!

Rosalind Franklin was born on July 25, 1920, in London, England. Growing up in a Jewish family with five siblings, she developed a passion for science at a young age. Encouraged by her parents, she attended St. Paul’s School for Girls, where she not only excelled in science but also became fluent in French, Italian, and German.

After completing high school, Franklin enrolled in Newnham College, one of the women’s colleges affiliated with Cambridge University. Her focus of study was physical chemistry.

During Franklin’s time in college, World War II broke out, leading to significant changes in her academic environment. Many of her professors left to contribute to the war effort, while others were detained due to their German heritage. One professor, Adrienne Weill, who was a Jewish refugee from France, became Franklin’s mentor.

Despite the challenges posed by the war, Franklin continued her studies and also served as an air raid warden. In this role, she provided first aid and extinguished fires caused by German bombs. She also reported bombing incidents to the Air Raid Wardens Service.

During her graduate studies, Franklin focused on studying the structure of coal, aiming to find ways to enhance its combustion efficiency. However, her research had an unexpected impact on the world. It contributed to the development of gas masks during World War II, as their filters utilized activated charcoal, influenced by Franklin’s findings.

Franklin became renowned as the first person to identify micro-structures in coal and other carbon-based substances. She successfully completed her dissertation and published five additional papers based on her research. In 1945, she obtained a Ph.D. in physical chemistry from Cambridge.

After the war, Franklin relocated to Paris for a few years before returning to England in 1949. She joined the team at King’s College in London, where she embarked on groundbreaking research concerning the structure of DNA.

Franklin utilized x-ray images to gain deeper insights into the nature of DNA. On May 6, 1952, she captured a groundbreaking image called Photo 51, which revolutionized scientists’ understanding of DNA’s three-dimensional structure. By combining this photo with her other data, Franklin worked tirelessly to unravel the secrets of DNA’s structure.

During the same period, two scientists named Francis Crick and James Watson were also studying DNA. In January 1953, one of Franklin’s colleagues shared her unpublished work with them. Thanks to the crucial contributions of Photo 51 and Franklin’s data, Crick and Watson published their own model of the DNA structure. Unfortunately, Franklin did not receive the credit she deserved for her significant role. Crick and Watson later received a Nobel Prize for their work.

Despite this setback, Franklin continued her research on DNA and also delved into studying viruses and the structure of RNA. Her groundbreaking work laid the foundation for future scientists studying viruses, including the one responsible for COVID-19.

In 1956, Franklin was diagnosed with ovarian cancer and tragically passed away two years later, at the age of 37. Today, she is remembered as one of the most brilliant scientists of her time.
