Claire Gruzelier was born and educated in Auckland, New Zealand and came to the United Kingdom with a Commonwealth Scholarship to study for a post-graduate degree in Classics at Oxford. She met her husband there and, after she gained a teaching qualification in London, they lived for a number of years in Cambridge. Here she began her teaching career and also had two daughters.
In 1994 the family moved to Birmingham and since then she has taught Classics at a secondary school here, as well as outreach at primary level and in adult education centres.
She has published books and journal articles on Silver Latin Epic poetry and helps edit the Classics magazine 'Omnibus'.
