1842–1916
A leading Victorian public-health doctor, he helped turn disease investigation into careful, evidence-based work. His career in sanitary reform and epidemiology made him an important figure in British medicine at the turn of the 20th century.

by Sir William Henry Power
Born in London on December 15, 1842, he came from a medical family and trained for the profession before building a long career in public health. He served the British Local Government Board, where he became known for investigating outbreaks and sanitary conditions with unusual care and precision.
Power was especially respected as an epidemiologist and sanitarian in late Victorian and Edwardian Britain. He was elected a Fellow of the Royal Society in 1895, appointed Companion of the Order of the Bath in 1902, and later knighted as KCB in 1908.
He died on July 28, 1916, in East Molesey, Surrey. Although not a household name today, he is remembered as one of the officials who helped make public-health science more systematic and influential in Britain.
