Leads for review

1. The inventor's own work

• French and Swiss family of the MWO patent: FR 732276 (filed 2 May 1931, published 15 Sept 1932), certificate of addition FR 42146E (filed 12 Feb 1932), Swiss CH 164027 (published 15 Sept 1933). The Swiss text names the apparatus's uses "comme agent therapeutique, ou comme source lumineuse pour la photographie, ou la cinematographie" and adds gas-filled glass tubes in the radiating part ("un veritable soleil artificiel"); the US 1,962,565 text has neither. Bears on claim 4 and on the deep-read finding that the US patent has no medical word. [web: https://patents.google.com/patent/CH164027A/fr]
• The open oscillating circuit is patented: CH 135072 (priority 26 Oct 1927; published 31 Aug 1929) / FR 657295. Claim: an open insulated circuit "qui ne comporte aucune source d'energie propre" shaped to surround the body; the plant spiral's natural wavelength "a peu pres 2 m"; collars and belts tunable by the clasp. Cites his own Academy note, C. R. Acad. Sci. 188, p.657 (1929). Bears on claim 3. [web: https://patents.google.com/patent/CH135072A/fr]
• Other own patents to read: FR 601155 (filed 18 Oct 1924, "devices generating electric oscillations by oscillating circuits"), FR 802262 (1935 "polymetallic circuit" for capturing waves), the silver sterilisation series 1929-1939 (FR 688887, CH 147806, FR 810280, FR 866036). Bears on claims 1, 3 and The Secret of Life's sterilisation experiment.
• Lakhovsky's own books not in the folder, now downloaded as text: L'Universion (1927, claim 5); Contributo all'eziologia del cancro (1927, Italian translation; soil and cancer, claim 5); Pour rester jeune a 100 ans: la spermatotherapie (1939, opens with cellular oscillation; claim 6). Cited but not found: L'Oscillateur a ondes multiples (Doin, 1932); La Science et le Bonheur (1930); "Sur la theorie du cancer basee sur la nature geologique du sol", Revue generale des Sciences, 15 Dec 1928; "Curing Cancer With Ultra Radio Frequencies", Radio News, Feb 1925.
• Kotzareff (1931) reports that Lakhovsky told him the Radio-cellulo-oscillator drew 40 W input power, and that he had used 2 to 10 m waves. The first power figure found; bears on whether the 1924 geranium effect could be thermal (claim 3).

2. Supporting information by others

• The 1924 note itself (CR Soc Biol 91, 626-628, 26 July 1924; Gosset, Gutmann, Lakhovsky, Magrou), as quoted in a 1925 press article: 3 treated pelargoniums (6 h, 33 h and 9 h of exposure), necrosis beginning about 16 days after the first session in each; 16 untreated controls all still growing tumours. Co-author J. Magrou (Pasteur Institute, Salpetriere laboratory) supplied the crown-gall tumours. Bears on claim 3. [web: https://www.colysa.ch/le-radio-cellulo-oscillateur-originel/; seller's site, an interested party]
• Kotzareff, Paris MD thesis 1931 (jury president J.-L. Faure): an independent physician with a rival method calls the 1924 note "seule et unique au point de vue experimental" and credits Lakhovsky with the first radio-cellulo-oscillator (1924), ahead of Schliephake; reports his own dogs, mice and clinical cases with ultra-short waves plus radon colloid therapy. Bears on claims 3-4.
• La Sante par les ondes (COLYSA, 1929): practitioners' letters, including Prof. Remond (Toulouse Faculty, Nov 1928), and the statement that Prof. Sordello Attilj (Santo Spirito hospital, Rome) presented a detailed report at the Florence radiology congress, May 1928. Published by Lakhovsky's company (stake). Bears on claim 3.
• Roussakow 2013 reads the 1924 work as a non-thermal RF effect ("mainly or entirely not temperature dependent"). Author has a position in the thermal vs non-thermal debate.

3. Closely related work

• Schereschewsky (US Public Health Service, Office of Cancer Investigations; later Harvard), Public Health Reports 1926 (vol. 41 no. 37) and 1928 (vol. 43): 8.3-135 MHz fields lethal to mice, destruction of mouse tumour grafts (23% complete remission at 67 MHz, per Roussakow) "without substantial heating"; he adopted the thermal explanation in 1933 after criticism. Same band as Lakhovsky's 150 MHz device; the thermal question is the same. [web: Roussakow 2013]
• Le Haut-Parleur no. 873 (13 July 1950) lists about 30 workers on biological effects of short waves after Lakhovsky (Seidel, Tisell, Rivera, Mezzadroli, Castaldi, Metalnikoff, Gianferrari, Saidman, Schliephake, de Cigna, Rigaux, Roffo, Postma, Karsis, Louste and others). A map of the field as seen in 1950.
• Reid 1989 (Med Hypotheses): a vortex-filament growth theory that names "Lakhovsky's non-linear oscillators" among regimes that might destabilise growth filaments. Hypothesis only.
• Later accounts with a stake: Brown, The Lakhovsky MWO Handbook (Borderland Sciences, 1994); EP 2862596 A1 (says the MWO "used cw systems with some (though limited) success"); commercial MWO sellers' "frequency analysis 20 Hz to 20 GHz" (altered-states.net, not opened).

4. The historical record

• Nature 146 (No. 3704, 26 Oct 1940), review by James Ritchie of The Secret of Life (Heinemann 1939): calls the filament model "so far removed from known facts"; identifies the Corynactis viridis "oscillating circuit" as the thread of a stinging cell (cnidocyst); grants the oscillator "apparently has worked marvellous cures" but says that does not prove the cell-oscillation theory; d'Arsonval's preface "frankly non-committal". The contemporary scientific press reception. Bears on claims 1 and 4.
• Company record: C.O.L.Y.S.A. (Circuit Oscillant LakhovskY S.A.), 26 rue des Marronniers, Paris 16e, 1929; Editions S.A.C.L., 25 rue des Marronniers, 1939. A present-day Colysa SA exists in Val-de-Ruz, Switzerland (Zefix; no Lakhovsky link in the entry), and colysa.ch sells Lakhovsky-type devices. Whether there is a line of succession is unknown (Paris Registre du commerce; Neuchatel cantonal extract).
• American end (absence of evidence): death 31 Aug 1942 at the Adelphi Hospital, Brooklyn, three days after being hit by a limousine; "George Lakhovsky Institute of Multiple Waves" founded in New York, January 1945 (ncip.by, a state IP office's unsigned biography). With US 2,351,055 assigned to Henry S. Blum of Chicago (1944), these are the records to pull: NYC death certificate and obituaries, New York State incorporation of the 1945 institute, Blum's business. Google gave nothing on Blum.
• Mainstream history: Farrell 1982 (Adv Exp Med Biol 157:9-10), a history-of-medicine note on Lakhovsky in a hyperthermia volume (not read); Stadler 2009/2010 Imperial College thesis places him beside Schereschewsky and Schliephake and cites de Kruif, New York Times, 22 Aug 1926.
• Google showed legal-removal (Lumen) notices on three Lakhovsky queries this run; content unknown.

• claims.md, claim 3 and facts.json (Radiations and Waves entry) name the 1924 collaborators as Gosset and Gutmann; the note has a fourth author, J. Magrou of the Pasteur Institute, who produced the tumours. Not an error so much as an omission; the treated-plant count (3, against 16 controls) is also not stated in claims.md.
