It is with regret that I write to inform you of the death of my father, Leslie James Harfield. He passed away on 18th May 2020 from what can best be summed up as 'old age'.  He was 90 years of age.
 
My father always spoke very fondly of his time at Churcher's. He joined the school during the Second World War in 1941. Having done well in both his School Certificate and the Higher School Certificate he remained on for a third year in the Sixth Form to study for and achieve a Major County Scholarship. During this time he was, for the last two terms, Captain of College. 
 
He was very grateful to the school for preparing him to apply, successfully, to Cambridge and for the opportunities it afforded him both academically and in other regards, in particular music and sport. I can remember watching him play cricket for the Old Boys at the school and so he must have maintained that active connection into the late 60s if not the early 70s. His love of music, in particular choral music, which started at Churcher's stood him in good stead when applying, again successfully, for a Choral Exhibition at Gonville and Caius. It stayed with him for life and he derived much enjoyment from it both as a participant and as a listener.
