Claridge was born at
RAF Hospital Halton; her father, John Claridge, a New Zealander from Wellington, was awarded the
DFC as a flight lieutenant bomber pilot, and subsequently rose to wing commander in the
RAF. Her Scottish mother, Marie (
née Cooper), was a flight officer working in intelligence at RAF Bottesford, Leicestershire. Claridge's parents separated, her father returning to his native New Zealand while her mother relocated to Italy. As a student Claridge's mother had volunteered on excavations under the direction of
Mortimer Wheeler, and this no doubt influenced Claridge to take an undergraduate degree at the
Institute of Archaeology in London (now part of UCL), where she was taught by Donald Strong, an authority in Roman art and architectural studies. == Career==
