Task: Question Answering
Input (English): Passage: Wheeler was keen to continue archaeological fieldwork outside London, undertaking excavations every year from 1926 to 1939. After completing his excavation of the Carlaeon amphitheatre in 1928, he began fieldwork at the Roman settlement and temple in Lydney Park, Gloucestershire, having been invited to do so by the aristocratic landowner, Charles Bathurst. It was during these investigations that Wheeler personally discovered the Lydney Hoard of coinage. Wheeler and his wife jointly published their excavation report in 1932 as Report on the Excavation of the Prehistoric, Roman and Post-Roman Site in Lydney Park, Gloucestershire, which Piggott noted had "set the pattern" for all Wheeler's future excavation reports.From there, Wheeler was invited to direct a Society of Antiquaries excavation at the Roman settlement of Verulamium, which existed on land recently acquired by the Corporation of St Albans. He took on this role for four seasons from 1930 to 1933, before leaving a fifth season of excavation under the control of the archaeologist Kathleen Kenyon and the architect A. W. G. Lowther. Wheeler enjoyed the opportunity to excavate at a civilian as opposed to military site, and also liked its proximity to his home in London. He was particularly interested in searching for a pre-Roman Iron Age oppidum at the site, noting that the existence of a nearby Catuvellauni settlement was attested to in both classical texts and numismatic evidence. With Wheeler focusing his attention on potential Iron Age evidence, Tessa concentrated on excavating the inside of the city walls; Wheeler had affairs with at least three assistants during the project. After Tessa wrote two interim reports, the final excavation report was finally published in 1936 as Verulamium: A Belgic and Two Roman Cities, jointly written by Wheeler and his wife. The report resulted in the first major published criticism of Wheeler, produced by the young archaeologist Nowell Myres in a review for Antiquity; although stating that there was much to praise about the work, he critiqued Wheeler's selective excavation, dubious dating, and guesswork. Wheeler responded with a piece in which he defended his work and launched a personal attack on both Myres and Myres's employer, Christ Church, Oxford. 
Question: What is the last name of the person who critiqued Wheeler's selective excavation, dubious dating, and guesswork?
Output (English): Piggott.
