Letter from Alan Lang Brown, Frithden, Hemel Hempsted to Howard Walter Florey Proposal which Florey mentioned, is to come before Henry Tizard's committee - will look through papers when they arrive - suggestion arose as result of visit of British scientists to America, when it became apparent that we were not in position to undertake pilot scale experiments on photosynthesis - therefore seems possible that scheme had its origin some time before their two Jewish friends met. 23 May 1951
