  • Martin Ruderfer person page [web] https://wiki.naturalphilosophy.org/index.php?title=Martin_Ruderfer. The current revision (oldid 333749, edited 16 Aug 2026) lists only "Events attended: United States Psychotronics Association Conference (1981)". A Google snippet of an earlier revision (dated 29 Jul 2026) read: "Died, May 1, 1982 (aged 62). Residence, Brooklyn, NY ... Martin Ruderfer worked at Dimensions, Inc., Brooklyn, NY", with an article list. These dates (born c.1919-20, died 1 May 1982) come from this one wiki source and its earlier revision; no second source has been found yet. An obituary (Newsday, NYT 1982) or the SSDI would confirm them.
  • Paper index entries (bibliographic only, no abstracts): "Comments on a New Experimental Test of Special Relativity" (1970, p.658); "Neutrino Structure of the Ether" (1975, p.9); "Comments on the Twin Paradox and Allen's Experiments" (1979, pp.327-330, 333-337); "Introduction to Ives' 'Derivation of the Lorentz Transformations'" (1979, pp.243-246); "The Fallacy of Peer Review" (1980, pp.533-562).
  • "Detection of Absolute Motion from Atomic Timekeeping Data", Speculations in Science and Technology 2(4), pp.385-386 and 405-420 (1979).
  • "Photon Found to be Composed of Neutrino & Anti-Neutrino", Energy Unlimited vol. 4, p.53 (1981).
  • Review of "Einstein Myth and the Ives Papers", SST 3(4) 439-448 (1980). A three-part exchange: Ruderfer's review; S. Richard Hazelett's comment (pp.442-444; Hazelett co-edited the book with Dean Turner, so he has a stake); and Ruderfer's "Reply to Hazelett on Einstein versus Ives" (pp.444-448). The wiki calls it "a dispute within the anti-relativity camp", and says Ruderfer "came to Ives as a partisan with a theory of his own" [web] https://wiki.naturalphilosophy.org/index.php?title=Review_of_%22Einstein_Myth_and_the_Ives_Papers%22
  • Ronald R. Hatch, "Comparing Spinning Mossbauer, GPS, and VLBI Experiments" (1st NPA Conference, San Francisco 1994). The abstract credits Ruderfer: "Ruderfer suggested that one could detect the variation of the transit time across either the radius or diameter of the spinning disk if an ether wind were present ... Ruderfer, in an erratum, pointed out that the two effects would cancel and render the experiment incapable of detecting an ether wind. In spite of this erratum, the claims are repeatedly found in the literature that the spinning Mossbauer experiments support the special theory. They do not. They are simply moot on the subject." [web] https://wiki.naturalphilosophy.org/index.php?title=Comparing_Spinning_Mossbauer,_GPS,_and_VLBI_Experiments. This is later support by others for claim 6, extended to GPS and VLBI (Very Long Baseline Interferometry). Hatch's Modified Lorentz Ether Theory (2002 ION paper, same wiki) is closely related work.
  • E. Preikschat, "Mössbauer Effect and Tests of Relativity", PhD thesis, University of Birmingham, 1968 (supervised by P. B. Moon and G. R. Isaak). A rotor Mössbauer aether-drift test giving a limit of (2.0 ± 5.2) cm/s [web] https://wiki.naturalphilosophy.org/index.php?title=Moessbauer_Effect_and_Tests_of_Relativity. This is one of the experiments that followed Ruderfer's 1960 proposal. How its interpretation relates to the 1961 point that "the effects cancel" is for the reviewers.
  • The wiki lists Ruderfer in its "Index of the Worldwide List of Dissident Scientists".

Bearing

Claim 6 (rotating Mössbauer cannot decide between ether and relativity): an independent later author (Hatch 1994) endorses it. Further work: Ruderfer's 1979 "absolute motion from atomic timekeeping" claims an ether detection from clock data, which goes beyond the 1961 position, and his 1980 "Fallacy of Peer Review ... a case history" is a record of how his work was received.
