Early attempts to observe electron polarization in the scattering of low-energy electrons from solids are reviewed. It is found that results published by Davisson and Germer in 1929 were analyzed incorrectly, and that they had in fact observed significant electron polarizations in the diffraction of low-energy electrons from single-crystal nickel.
