C.P. (Paul) Dillon, who acted as a consultant for the Nickel Development Institute (NiDI) and its successor, the Nickel Institute, has died. Mr Dillon worked with the NiDI right from its formation in 1985. He participated as a lecturer in NiDI’s Materials Engineering workshops in the US, Canada, and the UK, until his health prevented him from travelling in 1995. Paul continued to provide Nickel Institute technical service to enquirers to his last week. No doubt the high reputation that NiDI and the Nickel Institute has had for providing accurate and useful technical information is in large part due to Paul’s knowledge and abilities. Mr Dillon was the author of many books and technical articles, many published by NACE, MTI, and NiDI. He was made an MTI Fellow in 2001 in recognition of his critical involvement in the formation of that organization. He was also a NACE Fellow, a certified NACE Corrosion Specialist, and taught the NACE Basic Corrosion Course for many years. Mr Dillon worked for 34 years in Materials Engineering at Union Carbide (now a subsidiary of the Dow Chemical Company); this experience provided him with many insights into how materials perform in a corrosive environment.
