In the history of science, some names are known even to those with no connection to the field, while others are forgotten geniuses remembered only by specialists. The brilliant scientist Charles Glover Barkla belongs to the latter category. This Liverpool native made a discovery that fundamentally changed our understanding of X-rays, but sadly, his outstanding work remained in the shadow of his more fortunate colleagues. Yet, Barkla’s research laid the foundation for modern spectroscopy and earned him a Nobel Prize. Find out more on liverpool1.one.
Early Life
Charles Barkla was born in June 1877 in a suburb of Liverpool. His father, John Martin Barkla, worked as a secretary for a chemical company, and his mother, Sarah Frances Glover, was a homemaker. John Barkla, a practical and strict man, instilled in his son a love for discipline, reading, and new knowledge from a young age. His mother, who came from a family of clergy, tried to teach him kindness and spark his interest in the world around him.
The family wasn’t wealthy, but his parents did everything they could to give their son a good education. Even in school, he, much like the famous Liverpool actor Craig Charles, stood out for his unconventional thinking. Barkla also showed an unusual aptitude for natural sciences and mathematics, which made it easy for him to get into the University of Liverpool later on.
Charles’s childhood took place during Victorian Britain’s Industrial Revolution, when technological innovations were rapidly changing the country and the world. At the time, Liverpool was a very progressive city, a true centre of modernisation, which undoubtedly had an influence on the young Barkla. He devoured science books, attempted his own experiments, and dreamed of a career as a researcher.
At just 15, he was able to enter Liverpool Institute, and then the university, where his talents were fully unleashed. His parents made every effort to financially and morally support Charles in his studies, and their support became the foundation for his future discoveries.
Post-University Work and a Groundbreaking Discovery
After successfully finishing his studies at the University of Liverpool, the young researcher went to Cambridge, where he continued his scientific work under the supervision of Nobel laureate J.J. Thomson, the discoverer of the electron. Here, Charles focused seriously on studying X-rays, which had only been discovered by Wilhelm Röntgen three years earlier.
Barkla quickly realised that this field held incredible potential, so in 1902 he decided to move to the University of Liverpool to begin his own experiments. The young scientist sought to unravel the fascinating nature of X-ray radiation and figure out how to get the most benefit from this phenomenon.
Charles Barkla made his most important discovery in 1906, when he found that when X-rays pass through different materials, they produce unique spectra, which are characteristic of that particular element. They’re like “fingerprints,” but for a substance, not a person. This was a true revolution – now, the composition of a material could be determined simply by its radiation!
Working in a simple lab without expensive equipment, Barkla was able to prove that X-rays were not uniform or always the same, as was previously thought, but depended on the atomic structure of the material being analysed. A little later, in 1913, after Charles moved to the University of Edinburgh, he delved even deeper into his research, which laid the groundwork for X-ray spectroscopy.
Surprisingly, despite the significance of his discoveries, recognition for this talented man did not come immediately. He didn’t receive the Nobel Prize until 1917, and even this award didn’t make him a celebrity – his name was rarely mentioned in the press, and journalists didn’t line up to interview him. Barkla continued to work at the University of Edinburgh, studying the nature of atoms, light, and X-rays, and his name barely appeared in newspapers.
Life Beyond the Lab
While Charles Barkla was extraordinarily focused on science, he also made time for his personal life. In 1907, the scientist married Mary Cowell, the daughter of a Liverpool merchant, and their marriage was strong, peaceful, and happy. His wife fully supported her husband in his intellectual pursuits and managed to create a calm and cosy atmosphere at home that was conducive to scientific work. Despite his busy schedule, Charles always made an effort to pay proper attention to his family, especially encouraging the curiosity of their three children.
Barkla’s personal qualities can be understood through the memories of his friends and colleagues – they spoke of him as a kind, honest, and hardworking man. Charles always avoided the spotlight, preferring the quiet atmosphere of the laboratory to public appearances; he was not prone to academic intrigue and was always ready to help those in need. But he was also known for his strictness – Barkla demanded complete dedication and precision in research from everyone. Even after winning the Nobel Prize, he continued to live a modest life, believing that a scientist’s main goal was not fame, but the pursuit of knowledge.
Charles Glover Barkla went down in the history of world science as the scientist who unlocked the mystery of X-rays. Today, when you get an X-ray at the hospital, it’s probably worth remembering this humble genius whose discoveries advanced human knowledge, even if his name, for some reason, remained in the shadows.
