Germ Theory in Britain

Louis Pasteur’s germ theory, which proposed that microorganisms cause disease, had a profound impact on medical science. However, its revolutionary nature meant that it faced significant opposition, particularly in Britain, where some prominent figures resisted or outright rejected it. The debate between supporters and detractors of germ theory marked a crucial turning point in medical history, as new scientific understanding clashed with long-held beliefs.

Opposition to Germ Theory

Despite the compelling evidence put forward by Louis Pasteur and his contemporaries, many people were reluctant to accept germ theory. This resistance was particularly strong among some established British doctors and scientists, who clung to older ideas about the origins of disease, such as spontaneous generation—the belief that germs appeared spontaneously in decaying matter because of disease rather than being the cause of it.

Henry Bastian’s Opposition

One of the most vocal opponents of germ theory was Henry Bastian, an English surgeon and physician. Bastian rejected Pasteur’s ideas and instead championed the concept of spontaneous generation. He argued that germs were a byproduct of disease, appearing as a symptom rather than the cause of it. According to Bastian, the presence of microorganisms in diseased tissue was simply a consequence of the illness, not a factor in causing it.

Bastian’s opposition to germ theory was not limited to oral discussions; he actively published several books and articles in which he presented his arguments against the new theory. His influential position within the medical community allowed him to gain support from other professionals who were also resistant to the changes in medical thinking proposed by Pasteur and later, by Robert Koch.

Supporters of Germ Theory

While there was significant opposition, there were also many scientists and doctors in Britain who supported and promoted germ theory. Their work was crucial in overcoming resistance and advancing the understanding of disease causation.

John Tyndall and the Case Against Spontaneous Generation

John Tyndall, an English scientist, was an important figure in the fight to prove that germs caused disease. In his experiments, Tyndall placed various organic materials, such as meat and fish, in a wooden chamber filled with sterile air. These items did not spoil or go off, which demonstrated that microbes from the air were responsible for the decomposition of organic matter. When Tyndall exposed the same items to non-sterile air, they rapidly decayed, reinforcing the idea that germs were present in the environment and played a role in the spoilage and disease process.

Tyndall’s work helped to disprove the theory of spontaneous generation and provided strong evidence in support of germ theory. He shared his findings with Louis Pasteur, further strengthening the scientific case for germ theory and helping to convince many in the medical profession of its validity.

William Roberts and Support for Carbolic Spray

William Roberts, a Welsh physician, also played a significant role in supporting germ theory. In the 1870s, Roberts conducted experiments to disprove the idea of spontaneous generation, further cementing the argument that microorganisms were the cause of disease. In addition to his work on spontaneous generation, Roberts was a strong advocate for the use of antiseptics in surgery, particularly Joseph Lister’s carbolic acid spray.

Roberts recognised the value of carbolic acid in preventing infections in surgical wounds, which were frequently exposed to harmful germs in the operating theatre. He argued that Lister’s antiseptic approach could greatly reduce the risk of infection and save lives. His support for Lister’s work helped to build wider acceptance of antiseptic surgery and demonstrated the practical benefits of germ theory in medicine.

William Cheyne and the Spread of Antiseptic Practices

William Cheyne, a Scottish surgeon, was another prominent figure who embraced the ideas put forward by Pasteur and Lister. Cheyne worked closely with Joseph Lister, observing the effectiveness of carbolic acid in reducing infection during surgery. He became a staunch advocate for antiseptic techniques, believing that preventing infection in surgery was crucial to saving lives.

Cheyne also played a key role in translating the works of Robert Koch, a German bacteriologist, into English. Koch’s research on identifying the specific bacteria responsible for diseases was vital in advancing the understanding of infections and how they could be treated. By translating and disseminating Koch’s findings, Cheyne helped make the pioneering work of Koch accessible to British doctors, thus broadening the application of germ theory in the UK.

Cheyne’s contributions went beyond the operating theatre. He authored books on the use of antiseptics in surgery and continued to promote the work of both Lister and Koch. His efforts helped to spread the message that understanding and controlling germs was essential to improving medical practice and saving lives.

Conclusion

The introduction of germ theory by Louis Pasteur marked a turning point in the history of medicine, but it faced significant resistance in Britain. Figures like Henry Bastian strongly opposed the new theory, favouring outdated ideas like spontaneous generation. However, key supporters of germ theory, including John Tyndall, William Roberts, and William Cheyne, played a crucial role in challenging these beliefs and advancing the understanding of disease causation.

Through their experiments, advocacy, and promotion of antiseptic techniques, these scientists and doctors contributed to the gradual acceptance of germ theory in Britain. Their work helped lay the foundations for modern medicine, including the development of vaccines, antibiotics, and more effective surgical practices, ultimately saving countless lives.
