  We discuss the physical nature of elementary singularities arising in the
complexified Maxwell field extended into complex spacetime, i.e., in
Lanczos-Newman electrodynamics, which may provide a possible link between
elementary particle physics and general relativity theory. We show that the
translation of the world-line of a bare (e.g., spinless) electric-monopole
singularity into imaginary space is adding a magnetic-dimonopole component to
it, so that it can be interpreted as a pseudoscalar pion-proton interaction
current, consistent which both charge-independent meson theory and zero-order
quantum chromodynamics. On the other hand, the interaction current of an
electric-monopole intrinsic-magnetic-dipole singularity characteristic of a
Dirac electron is obtained by another operation on the world-line, which
however does not seem to have a simple geometric interpretation. Nevertheless,
both operations can be given a covariant interpretation, which shows that the
corresponding interactions necessarily arise on an equal footing, and therefore
provides a connection between elementary particles and singularities in general
relativity.
