Sir Flinders Petrie improved and pioneered the techniques and methods used in field excavations, now in standard use throughout modern archaeology. He was also a famous teacher and mentor of other archeologists. He is considered to be the father of Egyptian archaeology. At age 24, he wrote Inductive Metrology; or, The Recovery of Ancient Measures from the Monuments, which represented his new approach to archaeological study. In 1904, he published Methods and Aims in Archaeology, the definitive work of his time.
