Sir Thomas Morison Legge

Born in Hong Kong in 1863, Sir Thomas Morison Legge was the son of the noted scholar and missionary James Legge. He trained in medicine at Oxford and went on to become one of the key early figures in industrial hygiene and occupational medicine in Britain.

Legge is best known for serving as the first Medical Inspector of Factories and Workshops, a role in which he investigated dangerous working conditions and argued for practical ways to prevent illness on the job. He became especially associated with efforts to reduce industrial poisoning, including lead exposure, and his name lives on in the well-known "Legge's aphorisms," principles that stressed removing hazards at their source rather than relying only on workers to protect themselves.

Knighted late in his career, he is remembered as a careful doctor and reformer whose work helped move workplace health from neglect toward prevention. For readers interested in the history of public health, labor, or social reform, his life offers a window into the struggle to make modern work safer.
