  We review empirical and theoretical findings concerning white dwarfs in
Galactic globular clusters. Since their detection is a critical issue we
describe in detail the various efforts to find white dwarfs in globular
clusters. We then outline the advantages of using cluster white dwarfs to
investigate the formation and evolution of white dwarfs and concentrate on
evolutionary channels that appear to be unique to globular clusters. We also
discuss the usefulness of globular cluster white dwarfs to provide independent
information on the distances and ages of globular clusters, information that is
very important far beyond the immediate field of white dwarf research. Finally,
we mention possible future avenues concerning globular cluster white dwarfs,
like the study of strange quark matter or plasma neutrinos.
