## 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. In 1973, while working on Concorde's engines, he designed his first trigger probe. He worked on the Turbo-Union RB199 engine.
In 1973, he joined his former colleague John Deer to set up Renishaw plc. The company floated on the Unlisted Securities Market in 1983, and gained a full listing the following year. In 1987, McMurtry acquired the patents for his trigger probes from Rolls-Royce Holdings and began to exploit the patents himself. In 1989, he became a Royal Designer for Industry.
In 2018, McMurtry stepped down as chief executive of Renishaw and was replaced by marketing and sales director William Lee.
On 2 March 2021, McMurtry, along with John Deer, indicated that they wished to dispose of their entire holdings in Renishaw, comprising some 53% of the shares, as 'we recognise that neither of us is getting any younger'. 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.
In June 2024, McMurtry stepped down as executive chairman of Renishaw and remained on the board as a non-executive director.
