Recoil proton polarization was measured in deuteron photodisintegration at 90 deg. {sub cm} for photon energies up to 2.5 GeV. The induced polarization p{sub y} is consistent with zero above 1 GeV, consistent with expectations from quark models and in disagreement with meson-baryon calculations. Polarization transfer observables are non-zero, indicating that hadron helicity is not conserved.
