1873–1958
A pioneering British dental surgeon and bacteriologist, he wrote some of the early landmark books on oral bacteria, gum disease, and industrial lead poisoning. His work helped connect careful laboratory science with everyday public health problems.

by Sir Thomas Morison Legge, Kenneth Weldon Goadby
Born in 1873, Sir Kenneth Weldon Goadby built his career at the meeting point of dentistry, bacteriology, and preventive medicine. Early in the twentieth century he was associated with the National Dental Hospital, Guy's Hospital Dental School, the Seamen's Hospitals, and the London School of Tropical Medicine, reflecting how widely his expertise was used in both teaching and clinical work.
He is best known as the author of The Mycology of the Mouth (1903), an early and influential study of oral bacteria, and Diseases of the Gums and Oral Mucous Membrane (1923). He also co-authored Lead Poisoning and Lead Absorption with Thomas Morison Legge, extending his scientific work beyond dentistry into occupational health.
Goadby was later knighted, and his reputation was strong enough that the National Portrait Gallery holds portraits of him. He died in 1958, leaving behind a body of writing that shows how closely oral health, laboratory research, and public health were already connected in his era.
