- 1887 bridge-system paper: "This would have been the two brothers first joint publication ... but for OH's proposal that self-inductance, loading a circuit with inductance, could be a key contribution to decreasing and eventually removing distortion altogether. ... Preece, both as AWH's professional superior and as a well-respected figure in electrical engineering, blocked the paper's publication." "A joint paper by the brothers, to be published in the Journal of the Society of Telegraph Engineers, was blocked by Preece; instead, the theoretical aspect ... was eventually published in OH's 1893 ... Electromagnetic theory, volume 1, in which OH discussed self-inductance with leaks as it related to AWH's 'bridge system' as well as an additional proposal on how to achieve a distortionless circuit." AWH published his own part only in his 1900 IEE Newcastle address. Bearing on Records-that-go-quiet item 1: the manuscript's content was absorbed into EMT vol. 1 (1893) and the Electrician sections (see EP2 Sec. XL, archive-org notes). The manuscript itself: no location given.
- Footnote 18: IET SC MSS 005/I/1/12, notebook 1886-1889: "Complete MS copy of S[elf] I[nduction] of W[ires] (Right side) 163 pp Phil Mag and other papers some imperfect", transcripts of "On the Self Induction of Wires" Parts I-VII (Phil. Mag., Aug 1886 - July 1887), "and notes on the fate of Part VIII and Part XI [sic, probably IX], which were declined by the Philosophical Magazine and blocked by Preece, and partly published in The Electrician." A second blocked item: Phil. Mag. parts, not only the STE paper. (Compare EP2 Art. 38 "now first published".)
- Arthur's side: "Ultimately, however, AWH supported Preece against his own brother when it came to ... loading". OH's own words in 1922 (IET SC MSS 068, Highfield correspondence): "AWH was very afraid of P, who talked him over and convinced him that my theory was all theoretical bosh ... The greatest mistake AWH ever made was to throw me overboard, and go in for WHP." (Heaviside's characterization, 35 years later.) Bruton: "Reasoning from inadequate experiments, Preece declared inductance to be prejudicial to clear signalling" (her characterization).
- Earlier conflict with a documented stake: 1873, OH's duplex paper disparaged Culley's and Preece's duplex work and did not cite Preece's 1855 duplex patent. Preece to Culley: OH's paper "most pretentious and impudent ... He must be met somehow"; Culley: "We will try to pot Oliver somehow" (Bruton ref. [22], archival). OH admitted to the STE in Jan 1874 "in spite of the P.O. snobs".
- 1880 British patent no. 1407 (granted to OH alone; AWH as a GPO servant could not hold it), "Improvements in Electrical Conductors ...", which Bruton calls "essentially the patent for what later came to be known as a 'coaxial cable'". An own-work item not in the review. Recognised by C. S. Bright, Submarine Telegraphs (1898).
- GPO only engaged formally with Heaviside's work after Appleton (1924-25); a 1932 GPO report "The Application of the Heaviside Analysis to Electrical Engineering Problems", "no copies of which survive"; H. J. Josephs (GPO) wrote on Heaviside, "many based on papers of OH discovered under the floorboards of OH's former home in Paignton around 1957". This answers in part the arbiter's [memory, low] note about papers lost from his house: some papers were found later (Josephs), per Bruton.
- Kennelly published March 1902, Heaviside December 1902; Appleton's experiments "begun in late 1924".
- BT Archives references: TCB 274/1 (inductive telegraphy experiments 1886-1900), TCK 89/23 (Preece press cuttings), POST 30/2668B (patent rules for government servants).
Bearing
Claim 3: second academic account consistent with Hunt (blocked before submission, as superior). Adds the stake picture (1873 duplex dispute; Preece's public position), Arthur's role, a second blocked series (Phil. Mag. Self-Induction Parts VIII-IX), and exact archive references. Own work: the 1880 coaxial patent.
