We are very sad to hear the news that the co-founder and executive chairman of Renishaw, Sir David McMurtry, has died and we wish to acknowledge his many achievements in the field of measurement technology. Following an early engineering career in the aerospace industry, Sir David founded Renishaw to commercialise the 3-D trigger probe that he had invented whilst working at Rolls Royce. The company has become one of the world’s leading measurement technology companies based on continuous investment in research, product development and manufacturing. His obituary can be found here.
