Clement Dukes
Clement Dukes (1845-1925) was an English physician and dermatologist
Dukes was an educator, and public health advocate whose work reshaped the understanding of adolescent health and hygiene in boarding school environments. Best remembered for his tenure as medical officer at Rugby School (1871–1908), Dukes became a global authority on school health, combining clinical insight with epidemiological observation. His seminal work, Health at School (1887), influenced generations of educators and physicians and remains a milestone in the history of school medicine.
Trained at St. Thomas’ Hospital in London, Dukes graduated MB BS with honours and a gold medal in 1869, later obtaining his MD in 1876. His early hospital posts included St. Thomas’s, Great Ormond Street, the City of London Chest Hospital, and Moorfields. At Rugby, he served under four headmasters, implementing health reforms, isolation protocols, and dietary standards tailored to adolescent boys. His work was recognised with the Howard Medal (1884), Bisset-Hawkins Medal (1911), and a silver medal from the French Society of Hygiene.
Dukes also contributed to the fields of dermatology and infectious diseases. In a 1900 Lancet article, he distinguished between measles, rubella, and a third exanthem, proposing a “fourth disease” (later known as Filatov–Dukes disease). Although modern consensus largely dismisses the fourth disease as a separate entity, Dukes’ observations stimulated clinical debate and informed future understandings of paediatric rash illnesses. He published extensively, contributing to Allbutt’s System of Medicine and The Encyclopaedia of Medicine.
Beyond his medical duties, Dukes held roles as surgeon-colonel in the South Midland Brigade, consulting physician at the Hospital of St. Cross, and medical referee under the Workmen’s Compensation and Mental Deficiency Acts. A meticulous observer and prolific writer, Clement Dukes helped professionalise school medicine and advanced early paediatric dermatology. He died in Rugby on January 18, 1925.

Medical Eponyms
Dukes’ disease / Fourth disease (1900)
In a 1900 Lancet article, Dukes proposed a fourth exanthem, clinically distinct from measles, rubella, and scarlet fever. The illness presented with a mild rash, minimal systemic symptoms, and limited complications. Though historically cited as “Filatov-Dukes disease,” the entity is now widely regarded as a misclassification—likely overlapping with scarlet fever caused by Streptococcus pyogenes.
