Andrew Wallace-Hadrill is a British ancient historian and classical archaeologist born in Oxford on the 29th of July 1951. He is Professor of Roman Studies at the University of Cambridge and is known for his scholarship on Pompeii and Herculaneum, his sixteen-year directorship of the Herculaneum Conservation Project, and three documentary programmes for BBC television.
In a 2004 interview on the Australian television programme 60 Minutes, Wallace-Hadrill argued that Pompeii was suffering a "second death" caused by human neglect rather than natural forces. He stated that "Man is wreaking a damage far greater than Vesuvius" and warned that without constant conservation efforts the site would crumble to nothing within decades.
The Herculaneum Conservation Project is a conservation effort focused on Herculaneum, the Roman city destroyed by the eruption of Mount Vesuvius in 79 AD. Wallace-Hadrill directed the project from 2001 to 2016, and in 2011 published Herculaneum: Past and Future through Frances Lincoln to make the case for the site to a wider audience.
Wallace-Hadrill made three BBC television documentaries. The Other Pompeii: Life and Death in Herculaneum was first screened in April 2013. Building the Ancient City: Athens and Rome, a two-parter, screened in August 2015 and examined how the building of Athens and Rome paralleled the development of democracy in those cities.
Wallace-Hadrill was appointed an Officer of the Order of the British Empire in the 2004 New Year Honours for services to UK-Italian cultural relations. He won the Archaeological Institute of America's James R. Wiseman Award in 1995 for Houses and Society in Pompeii and Herculaneum. He was elected a Fellow of the British Academy in 2010 and received an honorary DLitt from the University of Reading in 2014.
Wallace-Hadrill studied Literae humaniores at Corpus Christi College, Oxford, then completed his doctorate at St John's College, Oxford, submitting his thesis in 1980. The thesis was titled "Suetonius on the emperor: studies in the representation of the emperor in the Caesars" and formed the basis for his 1983 book Suetonius: The Scholar and His Caesars.
