Beside his teaching career, Howgrave-Graham pursued his outside interests, one of which was the workings of medieval clocks. In the late 1920s he gave a lecture to a meeting of the St Albans and Herts Architectural and Archaeological Society on Richard of Wallingford’s astronomical clock. At that time, he had already submitted a paper to the Society of Antiquaries of London questioning widely held views concerning the earliest appearance of clocks in Europe and in England.
