   The Polarized Electrons for Polarized Positrons experiment at the 
injector of
the Continuous Electron Beam Accelerator Facility has demonstrated for 
the
first time the efficient transfer of polarization from electrons to 
positrons
produced by the polarized bremsstrahlung radiation induced by a 
polarized
electron beam in a high-$Z$ target. Positron polarization up to 82\% 
have been
measured for an initial electron beam momentum of 8.19~MeV/$c$, limited 
only by
the electron beam polarization. This technique extends polarized 
positron
capabilities from GeV to MeV electron beams, and opens access to 
polarized
positron beam physics to a wide community.
