Mr. John Dwyer was my lecturer when I did my Chemistry Degree at UMIST 1980 - 1983. He taught Chemical Reactor Theory which was really heavy going. He was a likeable fellow and very approachable. He was characterised by wearing a dark-grey suit and being slim and tall.
Thank-You Mr. Dryer for teaching me at one of the Finest Chemistry institutions in the world.
