Dr Harold R Allen came to Imperial College as a lecturer in October 1947, after completing a PhD at Cambridge's Cavendish Laboratory. He made major contributions to the Physics Department, but more importantly to the musical activities within the college. He became leader, organiser and treasurer of the college orchestra.https://blogs.imperial.ac.uk/videoarchive/files/2014/03/Allen2-300x240.jpg
