Norman E. Conner joined the North Western Gas Board as a student engineer in 1950 and began studying Mechanical Engineering at Warrington and St. Helens Technical Colleges. In 1953 he was awarded a Whitworth Society prize and a Technical State Scholarship to study Gas Engineering at the University of Leeds, graduating in 1957 with an Honors B.Sc., Degree. He returned to the North Western Gas Board as a production engineer in the South Lancashire group and was appointed Chief Chemist at the Warrington Production Station in 1958. In 1964 he left to take up an appointment as a Lecturer in Gas Engineering at the Royal College of Advanced Technology, Salford. He is a Chartered Engineer, a Fellow of the Institution of Gas Engineers and Managers and of the Energy Institute. He represented the University on the IGEM Education, Training and Academic Committees for many years and has been Chairman of the North Western Section of E.I., and the Manchester Gas Association. He received an M.Sc., Degree and Senior Lectureship in 1977. During his career he was actively involved in running Conferences/ Symposia in gas engineering, fuel utilisation and chemical engineering at the University. He is also a co-author of: Industrial Gas Utilisation Engineering Principles and Practice Bowker 1977. He was involved in setting up and teaching on the M.Sc., course in Gas Engineering and Management with colleagues (A.L Bowler and Dr. R. Pritchard) in the late eighties, later becoming Course Director. He is still actively involved in the Gas and Petroleum Engineering program at the University.
