Arrangement

Most of Sir John Cockcroft's papers were received from the Master's Lodge at Churchill College. His original filing system has been retained with only minor amendments to bring together files on the same subject and correspondence with the same individuals. In the later years of his life he had begun work on an autobiography and removed papers from the filing system to refresh his memory. These papers have been kept together and form section 25 of the catalogue.
