As part of the Cambridge Alumni Weekend 2009, Emeritus Professor John Davidson gave a talk entitled Chemical Engineering and Biotechnology: A merged Institution. Prof Davidson joined the Department of Chemical Engineering in 1952 as a University Demonstrator. He became Professor of Chemical Engineering (Shell Professor from 1978) and Head of Department from 1975 through to his retirement in 1993. He described some of his work over the years and demonstrated the basic principles of fluidised beds (as in the photograph). Prof Davidson ended his talk with a tribute to Dr Denys Armstrong, who was also a member of the Department for many years.
The talk took place on Friday 25 September 2009, at the Department of Chemical Engineering and Biotechnology, Cambridge.
It followed tours of the Department where alumni were shown some of the laboratories and given the chance to fire questions at researchers. Department staff and students joined the alumni for the talk, followed by a networking session over drinks and nibbles.
