  We report the optical discovery of the companion to the 2 M_sun millisecond
pulsar PSR J1614-2230. The optical colors show that the 0.5 M_sun companion is
a 2.2 Gyr old He-CO white dwarf. We infer that $\dot{M}$ during the accretion
phase is <10^{-2}\dot{M}_{edd}. We show that the pulsar was born with a spin
close to its current value, well below the rebirth line. The spin-down
parameters, the mass of the pulsar, and the age of the system challenge the
simple recycling model for the formation of millisecond pulsars.
