The implementation of fever wards at the Chester Infirmary in 1783 marked a pivotal shift in hospital management, yielding a recovery rate of nearly 97 percent for patients. John Haygarth, the physician responsible for this protocol, spent his career challenging existing medical assumptions through rigorous statistical observation and experimental practice across the United Kingdom.
Early Education and Career
Born in 1740 in Garsdale, Haygarth attended Sedbergh School where he was tutored by John Dawson. He entered St John’s College, Cambridge, in 1759, completing his studies there in 1766. Between 1762 and 1765, he attended the University of Edinburgh Medical School before pursuing further medical training at the University of Leiden and in London. In 1766, he received his MB degree from Cambridge and began his tenure as a physician at Chester Infirmary, where he remained for three decades.

Haygarth utilized data collection to refine public health interventions. In 1774, he conducted a census in Chester to track medical histories, identifying that fever patients required isolation to prevent transmission. He founded the Smallpox Society of Chester in 1778 to advocate for inoculation, a strategy that reduced local mortality rates by nearly 50 percent within four years. His 1784 work, Inquiry how to Prevent the Small Pox, utilized statistical calculations provided by John Dawson and influenced public health strategies in cities like Leeds and Liverpool. In 1793, he authored a plan for national inoculation, though his proposals faced resistance during the 1790s.
Investigating the Placebo Effect
In 1799, Haygarth investigated the efficacy of Perkins tractors, metal instruments marketed as curative devices for a high cost of five guineas. By conducting a comparative experiment using dummy wooden pointers, he demonstrated that patients reported identical benefits from the cheaper material. His findings, published in On the Imagination as a Cause & as a Cure of Disorders of the Body, provided a significant demonstration of the placebo effect. He concluded that the success of various medical treatments of the era was often psychological rather than medicinal.
Later Years and Legacy
Haygarth moved to Bath in 1798, continuing his medical research into rheumatic fever and gout. His contributions to the Philosophical Transactions of the Royal Society were complemented by his interest in social welfare, including the promotion of universal education and the establishment of local savings banks. He was elected a Fellow of the Royal Society in 1781 and a Fellow of the American Academy of Arts and Sciences in 1789. He died on June 10, 1827, and was buried at Swainswick.

Questions readers ask
What was Haygarth's primary contribution to fever treatment?
He demonstrated that isolating fever patients within a hospital setting significantly reduced mortality rates.
How did Haygarth prove the existence of the placebo effect?
He compared the effects of expensive metal medical tools with identical-looking wooden ones and found no difference in patient outcomes, attributing the results to the power of imagination.
