'Tizard and the Science of War'. The Tizard Memorial Lecture, delivered by Blackett at the Institute of Strategic Studies, February 1960. The folders of correspondence (H.85-88) contain reminiscences and information about wartime events in which Tizard played a part. In his letter to Admiral Middleton (H.87), Blackett writes 'I took a great deal of trouble in writing it, but feel it was very worth while because I wanted to put across what a terrific amount Tizard did for the country'. 1960
