He was brought up in Dublin and educated at Mountjoy School (now the Mount Temple Comprehensive School) in Dublin. McMurtry moved to the UK at the age of 18, in 1958.

Career McMurtry joined Bristol Aeroplane Company as an apprentice in 1958. In 1966, following an acquisition, he found himself employed by Rolls-Royce Holdings where he became Deputy Chief Designer and Assistant Chief of Engine Design at Filton.

The Renishaw board then announced that it was launching a formal sale process for the entire company. This process was terminated on 7 July 2021, after the board concluded that none of the proposals met their objectives.
