Richardson NCUACS 44/6/93 GENERAL INTRODUCTION PROVENANCE AND DESCRIPTION OF THE COLLECTION The papers were received in September 1993 from Mr O. M. Ashford, a colleague and close friend of Richardson and the Richardson family, who brought the material together over many years in the preparation of his biography of Richardson Prophet or Professor? The Life and Work of Lewis Fry Richardson (Adam Hilger, Bristol & Boston MA, 1985). An outline summary of the career of Richardson, drawing upon Prophet or Professor? and the Royal Society obituary of Richardson by E. Gold, Obituary Notices of Fellows of the Royal Society 9 (1954), is presented on page 5. The bulk of the papers were listed by Ashford in a 2pp manuscript note of ‘Material handed over to Cambridge University Library...23 Sep. 1993'. This may be found at A.2. Ashford's list divides the papers into 'Correspondence’, ‘Miscellaneous’ and ‘Original notes by LFR'. This arrangement has largely been followed in the presentation of this catalogue; the items listed under ‘Correspondence’ and 'Miscellaneous' comprise the bulk of the Biographical section of this catalogue, and the majority of the items listed by Ashford as ‘Original notes' are in the Notes and drafts section. Not all the and miscellaneous biographical material, Section A, Richardson.

F. Richardson NCUACS 44/6/93 Section B, Notes and drafts, comprises material ranging from manuscript jottings and research notes to lecture notes on differential equations 1937-1938 and drafts submitted for publication. The subjects relate to Richardson's meteorological and mathematical interests, to his study of war and to his interest in psychology. They include drafts of 'Gregariousness and its opposite’ and ‘Voting in an international organisation’. The material in this section is presented in chronological order. LOCATION OF OTHER MATERIAL list In Appendix E of Prophet or Professor? Ashford presents a very full of ‘Archives containing material relating to L F Richardson’ which he used in the preparation of his book, and the present collection includes photocopies of material held in some of these. his biography, pp. 240-241, many of Richardson's papers were destroyed after his death.
