Professor Arnold Dix (OH 1981), OHA Medallist, 2025
The medal was awarded for the 19th time at today’s Founders Day assembly in Aikman Hall, joined by former OHA Medallists, OHA Presidents, and members from the Class of 1986 celebrating their 40-year reunion.
Arnold became a hero when he helped rescue 41 Indian workers from a tunnel collapse high in the Himalayas. During the Silkyara Tunnel rescue in 2023, Arnold was the public face of the 17-day operation, declaring to the world from the beginning that the trapped workers would be rescued. Under his expert technical leadership and guidance, the operation switched to a slower, safer excavation technique after machinery failed – a mission-critical decision that prevented further collapse. Arnold’s optimistic attitude and calm approach built the confidence that the workers would come out alive.
An international tunnelling expert, Arnold established Underground Works Chambers, offering expert advice on high-risk subterranean infrastructure and safety regulation. Arnold has worked as a geologist, lawyer and barrister. He’s also dabbled as a flower farmer, truck driver and welder.
Arnold never asked for payment for his role in the rescue in India. He showed the world that good people working together can achieve the impossible.
Congratulations Arnold!
