Peter Halliday was a Welsh actor.
On leaving school he became an apprentice auctioneer with his father, but he had no desire to make it his career. He worked briefly for Rolls-Royce in Hucknall, Nottinghamshire before being called up by the Army during the Second World War, serving in Iraq, Palestine and Egypt.
While still in the Army he auditioned successfully for the Royal Academy of Dramatic Art while on leave. He joined the Shakespeare Memorial Theatre Company alongside Richard Burton, Michael Redgrave and Ralph Richardson. He played regularly at Theatr Clwyd for six years, and spent two years at the National Theatre.
In 1956, and at the height of his career, Halliday married Simone Lovell, daughter of the Canadian-born actor Raymond Lovell. The couple went on to have three sons, before divorcing.
He died on 18 February 2012 in London aged 87.
