Hi Kubur, I have found a much more likely candidate. Citing from Wikipedia: "Gayer-Anderson Pasha:
He joined the Royal Army Medical Corps in 1904 and was later transferred to the Egyptian Army in 1907. He was then promoted to become a Major in 1914 and during the same year, he became Assistant Adjutant-General for recruiting in the Egyptian Army. In 1919, he retired from the army to become the Senior Inspector in the Egyptian Ministry of the Interior, and he later became the Oriental Secretary to the British Residency in Cairo. He retired in 1924 but continued to live in Egypt, expanding his interests in Egyptology and Oriental Studies."
He stayed a long time in Egypt and was a known orientalist and a collector of weapons that are now presented in the Gayer-Anderson Museum in Cairo.
Could be him, but as said by David, not a very rare name, so it could be someone else..
