Leads for review

1. The inventor's own work

• Patents: seven US x-ray, film-carrier and filter patents (1911-1925) and five probable Canadian and French family members. The core ones are US1100037 (x-ray tube, filed 1911-02-23, granted 1914-06-16; lead-glass wall opaque to primary and secondary rays, a window passing only direct rays from the focal spot), US1372110 (radiating cellular diaphragm, filed 1919) and US1535359 (compensating x-ray filter, filed 1920). The film-carrier patents (US1370858, US1510424, US1527938, US1517767) cite his own 1915 edition pp.862-863. Bear on claims 2 and 5 (secondary radiation and the Tousey tube) and claim 4 (dental radiography). [web] research/2026-10-08-google-patents.md
• A second scan of the 1921 edition (IA medicalelectrici00tousiala, UCLA) contains the pages the folder's scan lacks: printed p.282-283 (electrotonus) and p.287 (concentration-cell membrane theory). Claims.md asks for exactly this. The 1910 and 1915 editions are also on IA. Bears on claim 7. [web] https://archive.org/details/medicalelectrici00tousiala
• Roentgenographic Diagnosis of Dental Infection in Systemic Diseases (Hoeber, 1916), with Tousey's list of 12 dental papers from 1904-1916. These include the dental-arch method, first found in J NY Inst Stomatology 1912 p.187 and read to the Angle School graduates in 1914 and the Harvard Odontological Society in 1915. Bears on claim 4. [web] https://archive.org/details/roentgenographic00tousiala
• "An Improved X Ray Generator", NY Medical Journal 97:648-649 (29 Mar 1913): Tousey's dated account of directing Sewall Cabot and Joseph T. Shaw to an "unfluctuating direct current" of 10-100 kV, with his physics reason (a spread of cathode-particle velocities gives mixed x-ray quality). It names "Doctor Williams, of Boston" as the person who first sent Cabot and Shaw to x-rays. Bears on claim 6. Interested party: Tousey has a stake in the credit. [web] https://archive.org/details/newyorkmedicaljo9719unse
• The Tousey unit, "A New Unit of X-ray Power", Archives of the Roentgen Ray 17:427 (1913). He was still using it himself in 1922: "3600 units of soft x-rays will produce severe dermatitis" (Am J Electrotherapeutics and Radiology 1922 p.386). Bears on claims 5 and 1 (it gives a dose number to set against his "never causes dermatitis" dose). [web] research/2026-10-08-google-books.md
• Medical Record 64:628 (1903): the beaker-interrupter paper behind the book's 1903 priority claim. It gives his posts in 1903 (Professor of Surgery and Rectal Surgery, New York School of Clinical Medicine). [web] Google Books snippet
• Papers held in archives: New-York Historical Society (small collection; typescript of "Protection of Patient and Operator in Radiography and Radiotherapy", Am J Physiologic Therapeutics 1911) [web] https://www.nyhistory.org/blogs/the-x-rays-of-melville-e-stone-jr ; UPenn Dental Library, Milo Hellman reprints collection, box 29 folder 40, "Tousey, Sinclair, 1906-1920" [web] https://archives.upenn.edu/collections/finding-aid/upc4_11/
• Thiosinamine monograph (1896) and Bratenahl and Tousey, Gynecology (1892): his surgical work before x-rays. [web] IA
• His own hands: "X-Ray Keratoses on Hand of Radiologist. Cured by Radium", Tousey's case report, Archives of Radiology and Electrotherapy 20(10):344 (1916): "his own hands had long been ..." Bears on claim 1 (operator safety beside patient safety). [web] https://academic.oup.com/bjrbir/article-pdf/20/10/344/57486712/are.1916.0084.pdf (not opened)
• Radium assay through the sealed tube (NYT 7 Jan 1914): he says he weighed French radium shipments without opening the tubes. Bears on claim 5 (his measurement methods). [web]

2. Supporting information by others

• Contemporary reception of claim 4: Int J Orthodontia 2(10):628-629 (Oct 1916) review: "from one of such eminence as Dr. Tousey"; recent pathology makes his reports "more convincing". Tousey cites Hartzell, Henrici and Leonard's counts (endocarditis in 23 of 31 cardiac cases). [web] IA sim_american-journal-of-orthodontics-and-dentofacial_1916-10_2_10
• Uptake of the Tousey unit (claim 5): abstracted in JAMA 60:1664 (1913) and the 1913 Yearbook of General Therapeutics; restated in J Florida Med Assoc 3:112 (1916); recorded by the historian R. F. Mould (1980 p.17; 2018 printing p.173). [web]
• Third party for claim 6: "Doctor Williams, of Boston", who per Tousey sent Cabot and Shaw to the x-ray problem; and Cabot's own 1912 converter patents (US1112436, US1191759), which do not mention Tousey. [web]
• Contemporary criticism, also pertinent (claim 3): AJMS July 1911 review of the 1910 edition. The neurologist reviewer finds many electrotherapy cures "not borne out by facts" though quoted "in good faith", and doubts the sciatica bath and scleroderma claims. [web] https://archive.org/details/paper-doi-10_1097_00000441-191107000-00023

3. Closely related work

• Albert C. Geyser's Cornell tube (1905 per Wikipedia), the rival contact tube in claim 2; Geyser, "Using the X-ray without burning", JAMA 1908; NYT 12 Apr 1908. Geyser is an interested party, as is Tousey. Geyser's later Tricho hair-removal system was criticized by the AMA (1925). [web] https://en.wikipedia.org/wiki/Albert_C._Geyser
• The electrostatic ("condenser") theory of x-ray burns was held by some early workers. Kienböck's 1900 experiments attributed the skin effect to dose, not electric phenomena (Widder 2014, PMID 25012643). This is the experimental record against which claim 2's condenser theory sits. [web]
• Present-day readers outside medicine: Firstenberg, The Invisible Rainbow (electricity and the ear); de la Peña, The Body Electric; Womack 2016 thesis on radiation therapy 1895-1925; Energetic Forum threads (electrophorus, Tesla/Oudin vacuum electrodes, Kapanadze), where the book is used as a reference on static and high-frequency apparatus. That is why it sits in the Energy folder. [web] research/2026-10-08-google-search.md

4. Historical record

• Life: born 1864; Columbia College of Physicians and Surgeons 1888 (ScienceDirect snippet; second source wanted); 1903 Professor of Surgery and Rectal Surgery, New York School of Clinical Medicine; addresses 59 W. 46th St (1909), 850 Seventh Ave (1914), Brooklyn and Westhampton Beach (1919), Garden City (1921-1937); summer resident of Whitefield, N.H. (White Mountain Echo 1926); gave $5,000 of radium to Morrison Hospital about 1931; died about 25 Sept 1937 (NYT obituary 26 Sept 1937). The record does not go dark: it continues to his death, including late fiction (Twin Strangers 1934, Love's Little Hour 1935, attributed in catalogues to "Tousey, Sinclair, 1864-").
• Wartime work: firearm-aiming and fire-control patents (filed 1917). This is a new side of the inventor; no war-contract record has been sought yet.
• Name confusion to guard against: the publisher Sinclair Tousey (1815/1818-1887, American News Company; probably his grandfather), and a Sinclair Tousey found dead in Yonkers in 1915 (NYT 30 July 1915). The Scar Book credits x-ray keloid treatment to "Sinclair Tousey (1818 to 1887)", conflating the two men.

Corrections to earlier documents

• claims.md, Source note: "obtain another scan of the same edition (HathiTrust or Internet Archive) for them [the missing pp.282-283, 286-287, 290-295]". Such a scan exists and has been located: IA medicalelectrici00tousiala (UCLA copy), whose text layer contains printed p.282-283 (ELECTROTONUS, ia-1921-ucla.txt line 17042 onward) and p.287 (the concentration-cell membrane passage, lines 17352-17430). The orchestrator may order a deep read of those pages (saved as research/pages/ia-1921-ucla.txt) so that claim 7's membrane account no longer rests on a gap.
• claims.md, claim 6: "the priority claim has no second source in the book". This is still true of independent sources, but there is now a dated 1913 statement by Tousey himself (NYMJ 97:648), which names a third party (Dr. Williams of Boston) and gives Cabot and Shaw's route to the idea. Add it as a lead; it is not independent corroboration.
• claims.md, Source note: "The folder contains no patent". This is true of the folder, but Tousey held seven US patents on x-ray apparatus and film carriers, the first filed 1911-02-23 (US1100037). Later steps should not infer from the folder that he had no patents.
