  Observations of pulsars with the Large Area Telescope (LAT) on the Fermi
satellite have revolutionized our view of the gamma-ray pulsar population. For
the first time, a large number of young gamma-ray pulsars have been discovered
in blind searches of the LAT data. More generally, the LAT has discovered many
new gamma-ray sources whose properties suggest that they are powered by unknown
pulsars. Radio observations of gamma-ray sources have been key to the success
of pulsar studies with the LAT. For example, radio observations of
LAT-discovered pulsars provide constraints on the relative beaming fractions,
which are crucial for pulsar population studies. Also, radio searches of LAT
sources with no known counterparts have been very efficient, with the discovery
of over forty millisecond pulsars. I review radio follow-up studies of
LAT-discovered pulsars and unidentified sources, and discuss some of the
implications of the results.
