He wanted to encourage a move away from purely classical education and offered a prize in history to pupils of Elstree Preparatory School.
In 1940 the number of participating schools had risen to 40, by which time both Henry and Marten had withdrawn.
The competition has continued to grow since then, and a special centenary competition was run in 1985. Notable winners, both from St Cyprian's, included Dyneley Hussey (1905) and Cyril Connolly (1916), with his colleague Eric Blair (George Orwell) in second place.
British Conservative Party politician Kwasi Kwarteng is also a recipient of the prize as he won it in 1988 while studying at Colet Court.
There are two exams in this competition, Paper 1 consisting of testing of dates and battles, and 2 is made up of essays.
