General Sir Charles Warren, was an officer in the British Royal Engineers. He was one of the earliest European archaeologists of the Biblical Holy Land, and particularly of the Temple Mount. Much of his military service was spent in British South Africa. Previously he was Commissioner of Police of the Metropolis, the head of the London Metropolitan Police, from 1886 to 1888 during the Jack the Ripper murders. His command in combat during the Second Boer War was criticised, but he achieved considerable success during his long life in his military and civil posts.

The Palestine Exploration Fund is a British society based in London. It was founded in 1865, shortly after the completion of the Ordnance Survey of Jerusalem by Royal Engineers of the War Department. The Fund is the oldest known organization in the world created specifically for the study of the Levant region, also known as Palestine. Often simply known as the PEF, its initial objective was to carry out surveys of the topography and ethnography of Ottoman Palestine – producing the PEF Survey of Palestine. Its remit was considered to fall between an expeditionary survey and military intelligence gathering. There was also strong religious interest from Christians; William Thomson, Archbishop of York, was the first President of the PEF.
