  The studies of solar neutrinos and helioseismology have been closely
intertwined since the first neutrino experiment and the first observations of
solar oscillations in the sixties. Early detailed helioseismic analyses
provided strong support for the standard solar model and hence a clear
indication that the solution to the discrepancy between the predicted and
observed neutrino fluxes had to be found in terms of neutrino physics, as now
fully confirmed by direct observations. With the full characterization of
neutrino properties we are now in a position to combine neutrino observations
and helioseismology to obtain a more complete understanding of conditions in
the solar core. Here I provide a personal and largely historical overview of
these developments.
