  We review the potential information that can be gleaned from multi-wavelength
and multi-messenger detections of Fast Radio Bursts (FRBs). The primary
function of such detections, following FRB localization, will be to reveal the
progenitors of FRB events. However, these observations serve a more basic
function in host galaxy identification, subsequent redshift measurement, and in
disentangling the contributions of various line-of-sight contributions to
properties of FRBs measured at radio wavelengths.
