Babbage's two lives

  • MENACHEM FISCH (a1)
Abstract

Babbage wrote two relatively detailed, yet significantly incongruous, autobiographical accounts of his pre-Cambridge and Cambridge days. He published one in 1864 and in it advertised the existence of the other, which he carefully retained in manuscript form. The aim of this paper is to chart in some detail for the first time the discrepancies between the two accounts, to compare and assess their relative credibility, and to explain their author's possible reasons for knowingly fabricating the less credible of the two.

6 It ended up in the hands of Harry W. Buxton, who testifies to have received from Babbage ‘some years before his death’ the ‘small MS volume … referred to at page 435 of the Passages from the Life of a Philosopher’, along with other papers, in order ‘that I should, after his decease, give to the world some account of his life and scientific labours’. Buxton, op. cit. (4), p. 3.

10 Snyder, Laura J., The Philosophical Breakfast Club: Four Remarkable Friends Who Transformed Science and Changed the World, New York: Broadway Books, 2011, points to several occasions in which Passages takes credit for the achievements of others, such as hosting the Sunday ‘breakfast club’ and masterminding the establishment of Section F of the British Association.

16 His obituary, published on 13 February 1857 in the Monthly Notices of the Royal Astronomical Society (1857) 17(4), pp. 98–99, talks laconically of ‘his college life’ exhibiting ‘faults of a very grave kind, to which we cannot avoid allusion, as their consequences were so notorious’.

17 Though Pollock, Frederick, Personal Remembrances of Sir Frederich Pollock, Second Baronet, Sometime Queen's Remembrancer, 2 vols., New York, Macmillan and Co., 1887, vol. 1, p. 40, deemed him ‘a person of little account’, Bromhead refers to him mockingly as ‘one very high man’. Bromhead to Babbage, 9 February 1816, British Museum Add Mss 37182, No 46, cited by Dubbey, John M., The Mathematical Work of Charles Babbage, Cambridge: Cambridge University Press, 1978, p. 62, who fails, however, to identify the ‘high man’ as Higman.

18 Buxton, op. cit. (4), juxtaposes the two accounts uncritically, giving 1811 as the purchase date when citing Passages (pp. 18, 21), and 1810 when citing MS 13 (p. 25). As editor, Hyman (Buxton, op. cit. (4), p. xv), overrules his author and sets the date consistently at 1810, including in his direct citations from Passages (p. 21).

19 Wilkes, op. cit. (4), p. 206; Grier, op. cit. (4), p. 20 n. 20; and Snyder, op. cit. (10), p. 30. Dubbey, op. cit. (17), p. 32, is more careful in this respect, but confuses the Lacroix purchased with the same author's Traité élémentaire de Calcul différentiel et de Calcul intégral, Paris: Duprat, 1802 (later editions published by Courcier), which he, Herschel and Peacock eventually translated.

20 See, for example, Herschel, John F.W., ‘On equations of differences and their application to the determination of functions from given conditions’, in Herschel, John F.W. and Babbage, Charles, Memoirs of the Analytical Society 1813, Cambridge, 1813, pp. 65114, 100 n.; Ortiz, Eduardo L., ‘Babbage and French idéologie: functional equations, language, and the analytical method’, in Gray, Jeremy J. and Parshall, Karen Hunger (eds.), Episodes in the History of Modern Algebra (1800–1950), Providence: The American Mathematical Society, 2007, pp. 1347, esp. 19–29; and Domingues, op. cit. (9), pp. 27, 200, 214 and 263.

21 Which explains why Enros, ‘The Analytical Society’, op. cit. (4), who relies heavily on MS 13, insists that the society was ultimately formed to promote research, not to reform Cambridge (e.g. Chapter 3).

22 Which, as I have noted elsewhere, is supported by external evidence. See Schweber, op. cit. (10), pp. 59–60, citing Maule to Babbage, 16 January 1812, British Museum Add MS 37182, f3.

23 MS 13 describes Bromhead's list of invitees as ‘those of his acquaintances who were most attached to mathematical subjects’ (24, emphasis added).

24 See especially Herschel, John F.W., ‘On trigonometrical series, particularly those whose terms are multiplied by the tangents, cotangents, secants, &c. of quantities in arithmetic progression, together with some singular transformations; with notes relating to a variety of subjects connected with the preceding memoir’, in Herschel, John F.W. and Babbage, Charles, Memoirs of the Analytical Society 1813, Cambridge, 1813, pp. 3364; ‘On a remarkable application of Cotes's theorem’, Philosophical Transactions (1813) 103, pp. 8–26; and Herschel, op. cit. (20).

25 This alone renders the MSS 13's dating of the formation of the society quite unrealistic.

26 The entire episode, pp. 32–37, is conveniently skipped by Buxton, op. cit. (4).

27 By contrast, the credit granted to Herschel in Babbage, op. cit. (13), pp. 393–395, is unqualified: Herschel's ‘excellent paper on functional equations’ (p. 394) is praised as correcting an oversight of Babbage's, and extending Laplace's ‘peculiarly elegant’ reduction of functional equations of the first order to those of finite difference, in a manner ‘equally elegant and quite general’.

28 MS 13 goes on the describe an additional method of Herschel's for solving Ψ2x = x again as an equation of finite differences. And, again, credits Herschel not for discovering, but for realizing, the viability of an approach they had both previously dismissed. Similarly, the ‘very ingenious mode’ of solving the equation Ψnx = x, proposed by Herschel ‘about this time’, is described as having been anticipated more generally by Maule in a letter of 15 May 1814 (pp. 67–76 [pp. 38–39]). See also De Morgan, Augustus, A Treatise on the Calculus of Functions (Extracted from the Encyclopaedia Metropolitana), London: Baldwin and Cradock, Paternoster Row, 1836, p. 14; and Grattan-Guinness, op. cit.
