Professor Sir William Matthew Flinders Petrie FRS (3 June 1853 - 28 July 1942), known as Flinders Petrie, was an English Egyptologist and a pioneer of systematic methodology in archaeology. He held the first chair of Egyptology in the United Kingdom, and excavated at many of the most important archaeological sites in Egypt, such as Naukratis, Tanis, Abydos and Amarna. Some consider his most famous discovery to be that of the Merneptah Stele, an opinion with which Petrie himself concurred.
