Musculoskeletal Disease History
Ancient Egypt and Roman-era skeletal remains; first formal written account by Francis Glisson, England, 1650
Rickets is a bone disease whose historical footprint stretches back to antiquity, though it rose to particular prominence during the Industrial Revolution when urban poverty and limited sunlight exposure made it devastatingly common among children in European cities. The story of rickets is fundamentally a story about how scientific communities slowly untangled the relationship between environment, nutrition, and human physiology over several centuries.
Historical Narrative
The earliest skeletal evidence suggestive of rickets has been identified in ancient Egyptian mummies and in archaeological remains from the Roman Empire, suggesting that the condition predates any formal medical description by thousands of years. However, the first recognizable written medical account is generally attributed to the English physician Francis Glisson, who published a landmark treatise in 1650 titled 'De Rachitide.' Glisson conducted systematic observations of affected children in England and produced detailed anatomical descriptions, giving the disease a formal medical identity for the first time. His work was so foundational that the word 'rachitic,' still used in historical and scientific contexts, derives from the Greek 'rachis,' meaning spine, which Glisson helped popularize in medical vocabulary.
During the 17th and 18th centuries, rickets was often attributed to a range of causes reflecting the medical thinking of the era, including poor maternal health, bad air, and hereditary weakness. The condition was sometimes called 'the English disease' by continental European physicians, partly because its prevalence in industrializing English cities was so conspicuous and partly as a somewhat unflattering geographic observation.
The Industrial Revolution dramatically worsened the condition's reach. As families crowded into smoky, narrow urban tenements with minimal sunlight exposure and diets dependent on cheap, nutritionally limited foods, rickets became epidemic across the working-class populations of Britain, Northern Europe, and eventually North America. Reformers and social observers of the 19th century frequently cited the bowed legs and skeletal deformities visible in children of industrial slums as visible evidence of the human cost of rapid industrialization.
The scientific unraveling of rickets accelerated in the early 20th century. Around 1918 and 1919, Edward Mellanby conducted a series of now-famous experiments with dogs in which he demonstrated that the disease had a clear dietary component, identifying that certain fats in food appeared to prevent it. Shortly afterward, Elmer McCollum, building on Mellanby's work, identified the protective factor as a substance distinct from the already-known Vitamin A, naming it Vitamin D in 1922. Concurrently, researchers including Kurt Huldschinsky in Berlin were demonstrating through clinical observation that exposure to ultraviolet light had a dramatic corrective effect on affected children, with Huldschinsky's 1919 experiments under mercury quartz lamps providing compelling photographic evidence.
The convergence of these two lines of inquiry — dietary fat-soluble substances and ultraviolet radiation — eventually led to the understanding that the human body could produce a necessary compound through skin exposure to sunlight, a remarkable biological discovery that fundamentally changed how physicians and public health authorities thought about the relationship between environment and disease. By the 1930s, the fortification of certain common foods with Vitamin D had begun in several industrialized nations as a public health measure, and rickets, which had been among the most widespread childhood conditions of the urban industrial world, began a historic decline. The history of rickets stands as one of medicine's most instructive examples of how a disease that seemed mysterious for centuries could yield to coordinated scientific investigation across multiple disciplines.
