Lieutenant-Colonel Sir Harold Arthur Deane KCSI (1 April 1854 – 8 July 1908)[1] was an administrator in British India.

The following year he became the first Political Agent of the Malakand and in 1896 he was appointed a CSI and then promoted to Lieutenant-Colonel in 1900.

In 1901 he became the Chief Commissioner of the North-West Frontier Province following its creation by Lord Curzon – a position he held until his death in 1908.

Deanne's remarkable collection of Gandharan and ancient Buddhist and Hindu artefacts, including three rare wooden panels from the Kashmir Smast, is now held by the British Museum.

[7] Deane fell ill in 1908 and returned to England, where he died two weeks later after being diagnosed with a brain tumor.
