William Henry Preece
Sir William Henry Preece (15 February 1834 – 6 November 1913) was a Welsh electrical engineer and inventor. Preece relied on experiments and physical reasoning in his life's work. Upon his retirement from the Post Office in 1899, Preece was made a Knight Commander of the Order of the Bath (KCB) in the 1899 Birthday Honours.

Preece was born in Caernarfon (Gwynedd), Wales, Great Britain. He was educated at King's College School and King's College London. Preece studied at the Royal Institution in London (Great Britain) under Michael Faraday. He later was the consulting engineer for the Post Office (1870s). He became Engineer-in-Chief of the British General Post Office in 1892. He developed several improvements in railroad signaling system that increased railway safety.
