|Description||Received by Blackett on the award of the Nobel Prize 91948), Copley Medal (1956), Companionship of Honour (1965), Order of Merit (1967), his election as President of the Royal Society (1965) and his elevation to the peerage (1969). Many of the letters are of interest for their biographical or historical reminiscences, discussions of scientific work, references to political activities or to social causes.|
The letters on the Nobel Prize were kept by Blackett in an alphabetically indexed box file. These have been removed to folders but retain Blackett's original ordering.
The letters on the Companionship of Honour, the Presidency of the Royal Society and the Order of Merit were kept in three large bulky-files each file has been split into nine smaller, alphabetically arranged folders for ease of reference. Letters of congratulation on behalf of corporate bodies are generally filed under the name of the organisation.
If Blackett sent a typescript acknowledgement, the carbon is attached to the letter. Most of the correspondence generated by the award of the Nobel Prize was answered in this manner, but letters re the later awards were answered by hand.
