The Early Years: Growing Up in an Influential Family

In the bustling city of London on July 25th, 1920, a brilliant scientist named Rosalind Franklin was born. She came from an influential British Jewish family, full of love and support. Her dad, Ellis Arthur Franklin, and her mom, Muriel Frances Waley, encouraged Rosalind and her siblings to learn and grow.

Rosalind was a curious little girl who loved asking questions about the world around her. Her family's passion for learning and helping others fueled her desire to explore the wonders of science. The Franklins believed that knowledge could make the world a better place, and Rosalind knew she wanted to be a part of that.

When Rosalind was old enough, she went to St Paul's Girls School, a prestigious school in London. She enjoyed her time there, discovering her love for science. She was especially fascinated by chemistry and physics, subjects that would later help her make groundbreaking discoveries.

While Rosalind was growing up, the world was facing a difficult time. The second World War had begun, and people everywhere were trying their best to support the war effort. Rosalind's family was no exception. Her father, Ellis Franklin, worked tirelessly to help refugees find a safe place to live. This sense of compassion and dedication to others inspired Rosalind throughout her life.

As Rosalind became more and more interested in science, she decided she wanted to study it further. Her family encouraged her to pursue her dreams, and she set her sights on attending one of the best universities in the world: Cambridge University. Little did she know that this decision would set her on a path to making history.

Paving the Way: Rosalind's Education and Pursuing Her Passion

Rosalind Franklin had big dreams and was ready to chase them. She went to Newnham College at Cambridge University to study science. Rosalind worked hard and soaked up all the knowledge she could. At Cambridge, she focused on physical chemistry, a subject that combined her love for chemistry and physics.

While studying at Cambridge, Rosalind was also involved in the war effort. She conducted research with the Coal Utilisation Research Association, studying British coal to help the country during World War II. Rosalind's work on coal taught her about solid organic colloids, a type of material that would later become important in her scientific journey.

After finishing her studies at Cambridge, Rosalind decided to learn even more. She traveled to Paris, France, to work with a talented scientist named Adrienne Weill. Under Adrienne's guidance, Rosalind learned about a powerful technique called X-ray diffraction. This technique allows scientists to take pictures of really small things, like molecules, to understand their shape and structure.

Rosalind also worked with another scientist named Jacques Mering. Together, they used X-ray diffraction to study the structure of various materials. Rosalind quickly became an expert in this field, and her skills would soon lead her to make groundbreaking discoveries.

While Rosalind was becoming an expert in X-ray diffraction, something big was happening in the world of science. Scientists all over the globe were racing to uncover the secrets of DNA, the building blocks of life. DNA is a tiny molecule that holds the instructions for making all living things, from plants to animals to people like you and me.

Rosalind's expertise caught the attention of a scientist named John Randall. He invited her to join his team at King's College London to use her skills to uncover the mysteries of DNA. Rosalind accepted the challenge, and her journey to unlock the secrets of life was about to begin.

The DNA Detectives: Rosalind Joins King's College London

When Rosalind Franklin arrived at King's College London, she was ready for a new adventure. She joined a team of scientists, including Maurice Wilkins and Raymond Gosling, who were also searching for the secrets of DNA. Together, they used X-ray diffraction to take pictures of DNA molecules, hoping to discover their structure.

Rosalind worked closely with a graduate student named Raymond Gosling. They were a great team, and Rosalind taught Raymond all about X-ray diffraction techniques. With Rosalind's expertise, they were able to take beautiful X-ray photographs that would help unlock the mystery of DNA's structure.

But the path to discovery wasn't always smooth. Rosalind faced challenges along the way. She didn't always get along with her colleague Maurice Wilkins, and they disagreed about the best way to study DNA. Despite these difficulties, Rosalind stayed focused on her work.

Meanwhile, in another part of England, two scientists named James Watson and Francis Crick were also trying to uncover the secrets of DNA. They knew that if they could figure out the structure of DNA, they could understand how life is built and how it grows.

One day, Rosalind and Raymond captured a stunning X-ray diffraction photo, which they called Photo 51. This picture showed the shape and structure of DNA more clearly than ever before. It was a major breakthrough, and it brought Rosalind one step closer to solving the mystery of DNA.

But Rosalind wasn't the only one looking at her photo. Without her permission, Maurice Wilkins showed Photo 51 to James Watson and Francis Crick. They were amazed by what they saw, and the photo helped them build a model of DNA's structure. This model, called the double helix, revealed how DNA's pieces fit together like a twisted ladder.

Rosalind continued her work at King's College London, unaware that Watson and Crick had seen her groundbreaking photo. She kept refining her own ideas about the structure of DNA, using her skills in X-ray diffraction analysis and her understanding of helical crystalline DNA.

A New Chapter: Birkbeck College and the Tobacco Mosaic Virus

After her time at King's College London, Rosalind Franklin decided to start a new chapter in her life. She moved to Birkbeck College in 1953, where she would continue her amazing work in science. At Birkbeck, Rosalind began studying a new mystery: the tobacco mosaic virus.

The tobacco mosaic virus, which is a part of the plant viruses family, is a tiny invader that attacks plants, making their leaves turn a strange, mosaic pattern. Rosalind wanted to understand this virus better, so she turned to her trusty X-ray diffraction techniques to take a closer look.

Rosalind's work on the tobacco mosaic virus was groundbreaking. She discovered that the virus had a unique structure, similar to a spiral staircase. This was important because it helped scientists understand how the virus could infect plants and cause disease.

During her time at Birkbeck College, Rosalind worked with a talented scientist named Aaron Klug. Together, they continued to study the tobacco mosaic virus, making important discoveries about its structure and how it worked. Rosalind's research on the tobacco mosaic virus laid the foundation for our understanding of many other viruses.

While Rosalind was making breakthroughs in her work on the tobacco mosaic virus, James Watson and Francis Crick were receiving recognition for their double helix model of DNA's structure. They, along with Maurice Wilkins, would later be awarded the Nobel Prize for their discovery. Sadly, Rosalind's important contributions to the discovery of the double helix were not acknowledged during her lifetime.

Rosalind Franklin's work at Birkbeck College was cut short when she became ill with ovarian cancer. Despite her illness, she continued to work and make important contributions to science.

Sadly, her illness continued to worsen, and she passed away on April 16, 1958, at the young age of 37. Her death was a huge loss to the scientific community.

What is X-ray diffraction?

X-ray diffraction is a special technique that scientists use to look at really tiny things, like molecules. They use X-rays, which are a type of light that can pass through solid objects, to take pictures of these tiny things.

When X-rays hit a molecule, they bounce off in different directions. Scientists can then measure how the X-rays bounce off the molecule to create a pattern. This pattern helps them understand the shape and structure of the molecule.

It's like shining a flashlight on a crystal and seeing a pattern of light on the wall behind it. That pattern helps you understand the shape of the crystal. X-ray diffraction is a bit like that, but with X-rays instead of a flashlight, and molecules instead of crystals.

Rosalind Franklin was really good at using X-ray diffraction to take pictures of molecules, which helped her make important discoveries about DNA and viruses.
