I would like to view the quantum mechanics paper "Über die Jacobischen Transformationen der Quantenmechanik," published in Germany in 1926 by Fritz Wolfgang London. The reference is Z. Phys. 1926, 37, 915–925. I searched for it online but couldn't find a free version. I also checked the Internet Archive but couldn't locate it there. If it is available somewhere, please let me know.

Incidentally, this paper is likely the first attempt to apply Hilbert space theory to the understanding of quantum mechanics. I am currently exploring how quantum mechanics was systematically developed mathematically by reviewing the papers from that era in order. I would appreciate your assistance.

    $\begingroup$ London published two papers on the subject in 1926, both are discussed by Lacki, which, I think, is freely accessible. But the copyright on the original papers is owned by Springer and they would not be freely accessible except through libraries or shadow sites like Sci-Hub. $\endgroup$

    $\begingroup$ 1926 is now at the copyright cut-off year for google-books availability (at least where I'm at), something that I especially keep track of since I don't have access to stuff behind paywalls. And when I checked at google-books (phrase search for title, restricted to 1920-1930; found volume 40 of the journal on the first page of hits; clicked on "More editions"; looked through the hits until I got to volume 37), I found it, which took all of about 45 seconds -- London's 1926 paper. $\endgroup$ Commented May 20 at 14:45
  • $\begingroup$ Thanks for helping me find the paper, Dave! Do you have the full text on your PC? I can't access it from my computer. I think it's because the phone number linked to resetting my Google account isn't associated with this one. My smartphone's a bit hard to use right now, so I'll try setting it up later. $\endgroup$

  • $\begingroup$ Hi, Jon. I'm residing in Japan, where there's a scarcity of proficient English-speaking librarians. Consequently, I can't depend on them extensively for research on English or German literature. $\endgroup$
