As the co-founder and long-time executive chairman of Renishaw plc, McMurtry played a pivotal role in shaping the metrology industry. His journey from an ambitious young engineer to a billionaire businessman is a testament to the power of invention, perseverance, and visionary leadership. This article explores McMurtry’s life, career, and the legacy that he has left behind in the world of engineering, highlighting his groundbreaking achievements, family life, and financial success.

Early Life and Education of David McMurtry

David McMurtry was born on March 5, 1940, in Clontarf, Dublin, Ireland. Raised in a family that valued education and hard work, McMurtry displayed a keen interest in engineering from an early age. His academic journey took him to Mountjoy School in Dublin, where he laid the foundation for his future career. At the age of 18, he moved to the United Kingdom to join the Bristol Aeroplane Company as an apprentice, marking the beginning of a long and successful career in the engineering sector. His work at Bristol and subsequent tenure at Rolls-Royce provided him with invaluable experience, and it was during this time that McMurtry would lay the groundwork for his most significant invention.

Career Beginnings: From Rolls-Royce to Renishaw

Before co-founding Renishaw, McMurtry worked at Rolls-Royce Holdings, one of the world’s leading manufacturers of aircraft engines. During his time there, McMurtry rose to prominence, becoming the Deputy Chief Designer and Assistant Chief of Engine Design at Rolls-Royce’s Filton plant. His expertise in engineering and design set him on the path to creating something truly groundbreaking.

McMurtry’s role at Rolls-Royce involved overseeing the development of engines for the Concorde supersonic aircraft. This period was crucial in shaping his vision for precision engineering. It was here that McMurtry began working on the touch-trigger probe, an invention that would eventually change the course of his career and the industry itself.

The Invention of the Touch-Trigger Probe

David McMurtry’s most significant contribution to the engineering world was the invention of the touch-trigger probe. This device revolutionized coordinate measuring machines (CMMs), allowing for the precise and repeatable measurement of complex components. Before this innovation, measurement systems were cumbersome and prone to error, which made it difficult to accurately assess intricate parts used in aerospace, automotive, and manufacturing industries.

The touch-trigger probe allowed for a more efficient and reliable measurement process, enabling industries to improve quality control and precision in their products. This breakthrough led McMurtry and his colleague John Deer to found Renishaw in 1973. Renishaw initially focused on the development of the touch-trigger probe and quickly established itself as a leader in the metrology field.

Renishaw: A Legacy of Innovation

Renishaw’s success was built on McMurtry’s invention and vision for the future. Over the years, the company expanded its product range, including machine tool probes, calibration systems, and additive manufacturing machines. Under McMurtry’s leadership, Renishaw grew from a small startup to one of the UK’s largest engineering companies, making significant contributions to industries like aerospace, automotive, healthcare, and manufacturing.

In 1984, Renishaw went public, listing its shares on the London Stock Exchange. This marked a new chapter in the company’s growth, and by the 1990s, Renishaw had become a key player in the global metrology market. Today, Renishaw continues to lead the way in precision measurement technologies and has expanded into healthcare, where it develops cutting-edge solutions for neurosurgery and other medical fields.
