Bertram Hopkinson's
main interest was in developing research in the Department, with the aim
of making it comparable with that of Experimental Physics at the Cavendish.
He built up a team of researchers looking at the science of flames and
explosions, as well as the impact of bullets on steel plates. Amongst
his research students was Harry Ricardo, the engineer who made his name
for his pioneering work on internal combustion engines. It was Hopkinson
who encouraged Ricardo to work on engines, turning him from the more traditional
pursuit of civil engineering at that time.
Hopkinson
continued his practice in the law courts together with his research.
He employed Arthur H. Chapman to help him, and Arthur went on to serve
successive Heads of Department for half a century. Bertram Hopkinson
devoted a great deal of personal attention to teaching, and intervened
personally in the running of the Workshops, appearing watch in hand
at 8am to check the workmen started on time.
