An exception to my claim is the essay in this volume by David Gooding, ‘History in the laboratory: can we tell what really went on?’, ‘Aurora, Nemesis and Clio’., 63-81. Gooding goes beyond the official accounts of experiments (performed by Faraday and Herschel). By examining notebooks and attempting to reproduce experiments under historical conditions, he gives new insights into the nature of Faraday's experiments and the laboratory culture in which they were performed.

7. It is not clear exactly how much money Crookes's father contributed towards his later house purchase, the construction and fitting of the attached private laboratory (modest at first) and the various business ventures. Fournier D'Albe, The brothers were associated with Griffin. (5), is vague on this, simply noting that help was given. Joseph Crookes was clearly very involved in the 1860s when his son attempted to promote a gold-refining process in South America.

It is an interesting cultural fact that chemists liked to portray themselves as living near the edge. In the same letter Crookes wrote of ‘generating smells and destroying furniture’.

He also kept a photographic record of apparatus and equipment used in his laboratory.
16. At the start of his career, in 1855, Crookes did spend one year as a science teacher at the College of Science, Chester, but by then he had already embarked on a variety of photography projects. In 1862 he gave a course of lectures with demonstrations to students of the Peckham Schools. See Fournier D'Albe, Crookes was an excellent scientific photographer. (5), 28 and 82.

Church was two years younger than Crookes and had also been a student at the Royal College of Chemistry. For a while he, too, was a close Crookes associate and a frequent contributor to Chemical News in its early days.

20. According to Fournier D'Albe, ‘The letters of William Crookes to Charles Hanson Greville Williams, 1861-2: the detection and isolation of thallium’. (5), 68, Crookes's right-hand man at the Chemical News at this time was W. T. Fewtrell.
21. He purchased the freehold for 20 Mornington Road, London (now Mornington Terrace), in 1861, though he had already been living there for about two years; see St Pancras Parish Register, 1862. It is likely that some family money went towards the purchase. He stated in one letter to Angus Smith that he had some private income; Fournier D'Albe, According to Fournier D'Albe. (5), 90. Since the rates for 1862, £56 per annum, were the highest in Mornington Road, the house must have been among the largest in what was a professional middle-class neighbourhood (inferred from St Pancras 1861 and 1871 census details). Crookes did not sell this house when he moved to Notting Hill in 1881 and owned it till his death.

23. There are frequent references in letters indicating that his wife, Ellen, dealt with much of his correspondence, for example a letter to his son, Henry, in Fournier D'Albe, He purchased the freehold for 20 Mornington Road. (5), 260. This letter also throws an interesting light on Crookes as a family man. He wrote lovingly about all the family members. Henry had been sent to Australia, partly for health reasons. Rayleigh makes reference to Ellen Crookes carrying out weighings in the laboratory. From the Crookes-Gimingham correspondence one has the impression that Crookes's mother-inlaw, Elizabeth Humphrey, was responsible for some of the accounts and that at least three of his sons helped with experiments. Science Museum Library MS409; Letters to Charles Henry Gimingham, 1871-77 (hereafter SML, Letters). The family economy pattern is not unlike some described in Leonore Davidoff and Catherine Hall, Family Fortunes: Men and Women of the English Middle Class, 1780-1850, London, 1987, part 2.

According to Fournier D'Albe, There are frequent references in letters indicating that his wife., 70, Crookes had a number of similar contracts but refused to put his name behind any promotion. Clearly this was prudent in someone wishing to make a name in science.
25. According to Fournier D'Albe, This contract brought in only about £20 per annum. (5), 86, in 1864 Crookes negotiated with the father of a prospective apprentice, Henry Seward, a pupil at the Peckham Schools where Crookes had given some chemistry instruction. I do not know whether the boy actually became Crookes's apprentice, but in a letter Crookes mentions a threeyear term at £500 per year.
26. There are many negative comments about Crookes in the published and archival material from this period. Oliver Lodge's nuanced foreword to Fournier D'Albe's biography, According to Fournier D'Albe. (5), is an example.
27. A photograph, taken later in life in his Notting Hill house, shows Crookes seated in a fairly large library. This was a working, not a self-improving, library and was situated next to his laboratory. The photograph was reproduced by Lord Rayleigh and shown during his presidential address to the Physical Society in 1936. R. J. Strutt, ‘Some reminiscences of scientific workers of the past generation, and their surroundings’, Proceedings of the Physical Society (1936), 48, 217-46.
28. Crookes, as a young man, may have felt ill at ease in the gentlemanly and club culture of early nineteenthcentury elite science. He did not, for example, take up many of the dinner and speaking invitations that came his way after the thallium discovery, and the reason cannot simply have been, as Fournier D'Albe put it, that Crookes needed to earn a living for his growing family. Others might have seen the social route as having professional and financial potential. Fournier D'Albe, A photograph, taken later in life in his Notting Hill house, shows Crookes seated in a fairly large library. (5), 65.

The last of these is interesting, and while it begins only in the 1890s, it starts, as did the correspondence with Crookes, much earlier, with flame spectroscopy.

According to Andrew Warwick (personal communication) Stokes was unusual among Cambridge mathematical physicists of the period in engaging in some experimental work.

38. Casual mention is made of two women glass-blowers employed from some time in 1881, the time when Crookes became seriously interested in electric lighting. The only one to be named was ‘Miss Stribling [who] made 24 lamp cases in 4 hours using up three cases of French Glass.’ Royal Institution, London, Laboratory Notebook, vol. VI, 1 June 1881-15 July 1884, entry for 8 March 1882. Some other employees will be mentioned below.

For the eclipse expedition see Fournier D'Albe, Casual mention is made of two women glass-blowers employed from some time in 1881, the time when Crookes became seriously interested in electric lighting. (5), ch. 11.
40. As a member of the board and as chemical advisor, Crookes earned £200 per year. In addition he was paid for on-site work, roughly £1000 per year. The firm also bought some of his patents, including one for a ‘carbolic sulphite deodorizer’ for £2200. Later in the decade he spent roughly the same amount of money to buy the English patent rights for a French sewage treatment method from Georges Fournier (Fournier D'Albe, On The Manufacture of Beet-Root Sugar in England and Ireland. (5), 268). Further, Crookes ran his own firm, Crookes and Co., for a few years during the 1870s; this promoted machinery for the digestion of animal refuse but proved unprofitable in the long run (On The Manufacture of Beet-Root Sugar in England and Ireland., 257-8). Chemical News brought Crookes an income of about £400 per year. Later (post-1880) Crookes's income was about £4000 per year (On The Manufacture of Beet-Root Sugar in England and Ireland., 378). It would appear that his income in the 1870s was roughly the same.
41. For details of the Native Guano Company see Fournier D'Albe, As a member of the board and as chemical advisor, Crookes earned £200 per year. (5), ch. 14. For a while this was successful, with several installations that Crookes supervised. For Crookes's electrical interests see As a member of the board and as chemical advisor, Crookes earned £200 per year., 291 and passim. In the 1880s Crookes became a director of the Electric Light and Power Company. He took out his first patent on a light bulb in 1881 when he established a lamp works in Battersea and made his son, Henry, manager. Unable to hold his own in this highly competitive field, he later sold out and also sold his patents (As a member of the board and as chemical advisor, Crookes earned £200 per year., 303-7).

43. There is no direct evidence for this but Fournier D'Albe, ’ History of the School of Chemistry at the Royal College of Science and its Predecessors during the Nineteenth Century’. (5), 85 shows how careful Crookes was in selecting an apprentice a few years earlier.

Reference to the ‘Sprengel’ is to the type of mercury pump used, one invented by Hermann Sprengel in 1865; it worked by allowing mercury to fall down tubes, capturing air (between drops) as it fell.

49. Mrs Humphrey was Crookes's mother-in-law. She appears to have had some role in ordering, and paying the bills of suppliers-at least while Crookes was away. There are several references to this. See, for example, SML, Letters, 5 November 1872, Paris. The reference to ground rents here and elsewhere suggests Crookes was a landlord.
50. SML, Letters, 18 October 1871, Manchester, and 27 September 1872, Paris. I think the new baby followed in his brother's footsteps and became a glass-blower with Edison and Swan. There are references to a Mr E. Gimingham having come from Edison and Swan to do glass-blowing for James Dewar at the Royal Institution. Also, William J. Green, an assistant at the Royal Institution, in a letter to Lord Rayleigh, 2 May 1940, mentions Mr E. Gimingham as being a ‘hale old man’ with a business in Diverton. See Royal Institution, Dewar Papers, DE 9/3/2 and DE 16/2/38.
51. SML, Letters, 27 January 1872, Mornington Road. The ABC (alum, blood, charcoal and clay) process, developed in the 1860s, was designed to treat sewerage and convert it to saleable manure. The process had been invented by W. C. Sillar; see Fournier D'Albe, I think the new baby followed in his brother's footsteps and became a glass-blower with Edison and Swan. (5), 257-9. Crookes had to deal with several disputes over the quality and safety of the manure. The reference to a second ‘lieutenant’ is one of several references to other workers. This one was called Mr Slater. By April 1872, Crookes was using a monogrammed letterhead. It consisted of a cross above which was a small elephant. His initials are entwined around the cross on which is inscribed ‘ubi crux ibi lux’. Later, when knighted, Crookes used this as his heraldic emblem. It would be good to know what his peers thought of it. Crookes appears to have been very careful of his reputation so one must conclude that’ respectable’ taste has changed. Though perhaps not; in Our Mutual Friend, Charles Dickens made fun of the Veneerings for a similar vanity.
52. SML, Letters, 7 November 1872, Paris. Crookes was happy with the installation. ‘The process works very nicely and the water is very good. Fish are living nicely in the third or fourth trial. On Wednesday we begin to receive official visitors.’
53. W. Crookes, ‘On attraction and repulsion resulting from radiation’, Philosophical Transactions (1874), 164,501-27. A version of the paper titled ’ On the action of heat on gravitating masses’ had been read at the Royal Society, 11 December 1873, and was published in Proceedings of the Royal Society (1873), 22. It was later summarized and serialized by Crookes in Chemical News. He did this for all the papers in the series. For a full account of Crookes's work, see the papers published in Phil. Trans, between 1874 and 1881. These papers are remarkable for their fine and very detailed description of experimental procedure. Crookes was undoubtedly making a statement about what it takes to do the kind of vacuum studies he was engaged in. It is possible to read his very good descriptions of the finesse needed, as a not-too-subtle message telling others that the field was so difficult they would be wise to stay away. Another interesting point, not acknowledged by earlier historians, is that Crookes and Gimingham were already experimenting with the torsion balance in 1872. Crookes did not mention this new apparatus in print until the submission of an abstract to the Proc. Roy. Soc, 20 March 1875. The 1874 Phil Trans, paper described a series of experiments in which heat repelled an object suspended at the end of a regular balance beam. In his second paper in the series, Crookes does mention that he had discarded the traditional balance form of apparatus even before his first paper was read to the Royal Society and that some early versions of the new apparatus had been displayed on 11 December 1873. See paragraph 84 in W. Crookes, ‘On repulsion resulting from radiation, Part II’, Phil. Trans. (1875), 165,519-47. It is clear, however, that in these 1873 demonstrations, Crookes was still holding much back.
54. Crookes's original vacuum balance was from Oertling and the weights from Johnson and Matthey were made of platinum and manipulated from outside the evacuated case. But by this time (1872) very simple balances that could be enclosed in blown tubes had been devised and were being improved on-as were appropriate measuring procedures.
55. SML, Letters, 27 September and 5 November 1872, Paris. The ‘neutral point’ was the point (in evacuation) at which change in the direction of movement in the pith balls (and other objects), occurred when hot (or cold) objects both within and without the evacuated tubes, were brought close (see published papers for details). Crookes obviously wanted to keep the details to himself at this time. In a letter from Paris, dated 3 November, he wrote that Huggins wanted to see the Sprengel pump but ‘don't tell him too much about the neutral points and repulsion by heat experiments’. William Huggins was a wealthy brewer, an amateur astronomer, a vicepresident of the Royal Society at this time, and had taken part in some of Crookes's spiritualist activities.
56. SML, Letters, 9 October 1872, Paris.
57. Crookes's speculations and those of others have been widely discussed in the literature. See, for example, DeKosky, SML, Letters. (45). It is clear that Crookes did a literature search because he began his own series of papers with a discussion of historically related precedents, including the work of Fresnel and of the Rev. A. Bennett, FRS, whose magnetism experiments of the 1790s appear to have been very suggestive methodologically. Because he believed he had a good vacuum, Crookes speculated along two lines. First, that heat might affect the gravitational force and secondly, that heat had a direct mechanical effect on the weights (pith balls, or whatever). He and Gimingham also early experimented with spring balances because Crookes thought beams might expand with heat, but they gave these up as impractical.

The theorist in question was Osborne Reynolds who, after watching Crookes's demonstrations and doing some experiments of his own, had come to the conclusion that kinetic theory could be used to explain the heat effect. Debate at the time was over the role, if any, of residual gas on the heat/motion phenomenon. As indicated above, Crookes used experiments he had performed earlier to counter some of Reynolds's claims.

69. Some examples: for beams he tried glass, mica, straw and brass; for suspension, spider web, cocoon thread; and for terminals, pith, cork, ivory and metals. For terminals they came to use ones with a large surface and minimum weight; earlier Gimingham had cut discs from butterfly wings, pressed rose leaves, thin split mica and other materials. See Crookes, ‘On repulsion’, ‘Apparatus for measurement of low pressures of gas’. (53). Joseph Hooker sent pith specimens from papyrus plants at Kew (SML, Laboratory Notebook IV, 3 March 1876).

Stokes did not know of Kundt and Warburg's work until the end of 1876 and so some of the suggestions he gave Crookes that year were inappropriate. See, for example, Larmor, ‘The radiometer and its lessons’. (34), ii, 393: Stokes to Crookes, 23 January 1877. Maxwell's theory did not apply at very low pressures, but Crookes and Gimingham were far from having a very good vacuum.

The huge amount of data generated in this project, data that had to be reduced by arcane mathematical procedures, might well be considered in the way suggested by Latour and Woolgar.

(34), ii, 383: 16 May 1876). Crookes probably did not have the time for this. Crookes's sons Henry and Bernard also helped out in the laboratory.

88. See, for example CUL, C1096, 29 April 1876. Gimingham also made radiometers for a number of other people, including the Emperor of Brazil. He was probably the source of the radiometers acquired by Maxwell for the Cavendish in 1877, and mentioned by Brush and Everitt, SML, Laboratory Notebook IV. (71), 112.
89. A small income could be made from such demonstrations. In a letter to Professor Johnstone Stoney of Queen's University, Dublin (the precursor of University College Dublin), Crookes asked for expenses and an honorarium of £25 for a lecture demonstration (or £35 for two). Fournier D'Albe, Gimingham also made radiometers for a number of other people, including the Emperor of Brazil. (5), 298.
90. Fournier D'Albe, A small income could be made from such demonstrations. (5), 255.
91. One such display was held at the Royal Society soiree, 5 April 1876. But Crookes also displayed at the Royal Institution, the London Institution and other locations. At a Royal Institution lecture in 1879, Crookes had fourteen different demonstrations, all quite complex. See SML, Laboratory Notebook II, 12 February 1879. Every now and then the notebooks show lists of things to prepare for such demonstrations, and reminders to make ‘please do not touch’ labels.
92. Crookes also wrote about these to Stokes. CUL, Stokes Correspondence, C1103 and C1105, 19 May and 23 May 1876.

101. Crookes was in Manchester and Glasgow during February, Brussels in April, Paris for all of July and much of August, and again in December. Fournier D'Albe, CUL, Stokes Correspondence. (5), 271, mentions Gimingham working in a laboratory in Boy Court (the City location of the office of Chemical News) at this time. I have found no other evidence for this claim.

The folk wisdom is that Crookes's Notting Hill house, 7 Kensington Park Gardens, was the first in England to have had electrical lighting. I do not know how far the two got with the electrification of 20 Mornington Road.

120. The phenomena are well known and will not be described here. Crookes's paper, sent to the Royal Society, 30 November 1879, was entitled, ‘On the illumination of lines of molecular pressure and the trajectory of molecules’, and published later in Philosophical Transactions of the Royal Society (1880), 170, 135-64.

125. CUL, Stokes Correspondence, C1150, 26 April 1879. Maxwell had written a report on Crookes's paper, ‘Contributions to molecular physics in high vacua’, submitted to the Royal Society in March 1879. He allowed the report to be passed on to Crookes, which may have prompted the letter to Stokes. See Larmor, CUL, Stokes Correspondence. (34), ii, 427.

Later, all his important speeches and papers were vetted by his friend Alice Bird, whom he relied on to correct his grammar and polish up his phrases. He had met Miss Bird around 1870 when she became interested in his spiritualist research. She and her brother remained very close friends with the Crookes family.

130. Gimingham set up the company's lamp factory at Benwell, Newcastle upon Tyne. There he introduced a five-tube form of the Sprengel pump which became an industry standard for evacuating incandescent lamps. The original company was bought up by the Swan United Electrical Light Company and Gimingham then became manager of the Benwell factory. It was this company that amalgamated with the Edison Company. Gimingham moved to London in 1886 and supervised the planning of a new factory for the Edison and Swan Company at Ponders End. See Obituary, Strutt, Later, all his important speeches and papers were vetted by his friend Alice Bird, whom he relied on to correct his grammar and polish up his phrases. (37).
131. It is interesting to note that the chemical notebook, 7 February 1881-7 July 1883, appears to be written almost entirely in Crookes's hand (SML Laboratory Notebook III: it deals with his work on samarskite and the citron band. Crookes worked on a large scale, making extractions from several pounds of ore). The earlier notebooks are almost entirely in Gimingham's hand. There is a chronologically overlapping notebook (Royal Institution, Vol. VI) dated 1 June 1881-15 July 1884) in which Gimingham made several entries before he left Crookes's employment: he was making incandescent light bulbs, carbonizing threads and blotting paper; blowing a variety of shapes of bulbs and figuring out how to seal filaments in them. As mentioned, Crookes had an interest in the electric light industry and held several patents, which he later sold. Gimingham was obviously a good catch for the Swan Company.

139. He did publish at least two papers: C. H. Gimingham, ‘Contribution to the development of the Sprengel air pump’, Society of Chemical Industry journal (1884), 3, 83-9, and J. A. Fleming and C. H. Gimingham, ‘On some instruments for the measurement of electro-motive force and electrical power’, Philosophical Magazine (24 November 1887), 522-38. John Ambrose Fleming (1849-1945) was a professor in Nottingham who later joined the Edison Electric Light Company. In 1885 he became professor of electrical technology at University College London.
