Flinders PetrieSir William Matthew Flinders Petrie, FRS, FBA (3 June 1853 – 28 July 1942), commonly known as Flinders Petrie, was an English Egyptologist and a pioneer of systematic methodology in archaeology and preservation of artefacts. He held the first chair of Egyptology in the United Kingdom, and excavated many of the most important archaeological sites in Egypt in conjunction with his wife, Hilda Petrie. Some consider his most famous discovery to be that of the Merneptah Stele, an opinion with which Petrie himself concurred.
Petrie developed the system of dating layers based on pottery and ceramic findings. Provided by Wikipedia
