1. Among those sources that deal with Marconi's first transatlantic telegraphy are Vyvyan R.N.Wireless Over Thirty YearsLondon 1933 23 33 B. L. Jacot and D. M. B. Collier,Marconi, Master of Space: An Authorized Biography of the Marchese Marconi(London, 1935), 62–85; Orrin E. Dunlap,Marconi: The Man and His Wireless(New York, 1937), 87–102; R. Danna, ‘The trans-atlantic radio telegraphic experiments of Guglielmo Marconi, 1901–1907’, unpublished PhD thesis, University of Missouri, 1967, 26–33; Howard Clayton,Atlantic Bridgehead: The Story of Transatlantic Communication(London, 1968), chapter 7, ‘The first transatlantic wireless messages’, 133–50; W. J. Baker,A History of the Marconi Company(London, 1970), 61–73; W. P. Jolly,Marconi(London, 1972), 85–114; Charles Süsskind, ‘Guglielmo Marconi (1874–1937)’,Endeavour, 33 (1974), 67–72; Keith Geddes,Guglielmo Marconi, 1874–1937(London, 1974), 14–20; Hugh G. J. Aitken,Syntony and Spark: The Origin of Radio(New York, 1975), 261–5; Degna Marconi,My Father, Marconi, 2nd edn (Ottawa, 1982); and G. A. Isted, ‘Guglielmo Marconi and the history of radio—Part II’,GEC Review, 7 (1991), 110–22, especially 110–12. For Marconi's own accounts, see his letter inNew York Herald(17 December 1901); Marconi, ‘Address’ (delivered at the annual dinner of the AIEE on 13 January 1902),Transaction of the American Institute of Electrical Engineers, 19 (1903), 98–101; and Dunlap's interview with Marconi in hisMarconi, 94–8,passim.
2. Among the secondary literature quoted in note 3, only Vyvyan, Baker, and Aitken duly appraise, though very briefly and often incorrectly, Fleming's role in the Poldhu experiment. Both Baker's and Aitken's source are Vyvyan who had assisted Fleming at Poldhu in the winter of 1900/1901 and borrowed The History of Transatlantic Wireless Telegraphy from Fleming in preparing Wireless over Thirty Years. Fleming's own account was published briefly in Fleming John AmbroseThe Principles of Electric Wave TelegraphyLondon 1906 44 45 69–70, 449–52. A yet more detailed account can be found in an unpublished manuscript, John Ambrose Fleming, ‘The history of transatlantic wireless telegraphy’, vol. I (manuscript narrative by Fleming covering the years 1898–1902, n.d.), University College London [hereafter UCL] MS Add. 122/64, Fleming Collection. Fleming's manuscript notebook of the Poldhu experiment, ‘Notebook: Experiments at UCL and at Poldhu’, UCL MS Add. 122/20, Fleming Collection, is another valuable source.
