Who originated Taylor's axiom of lunar formation, and where?
Just a shot in the dark, as the journal in which this article has been published has no online presence and is not available in paper form in my institution, but it might refer to an article by a Richard L. S. Taylor from 1990 called 'The Damocles Hypothesis', published in the journal "Space" (journal edited by the University of London it seems). 

Follows the abstract of that article:


  Consideration is given to the use of data from the Apollo missions to
  study theories of the origin and geological evolution of the moon.
  Theories of lunar origin are examined, including origin by fission,
  binary accretion origin, the capture hypothesis, and the giant impact
  model. Apollo data related to each of these theories is summarized,
  showing that the giant impact model is the most probable theory for
  the origin of the moon. The giant impact model is outlined, focusing
  on the collision between the earth and a large body called Damocles.
