2005; di Serego Alighieri [[et al. ]{}]{}2005; Jorgensen [[et al. ]{}]{}2006). In van Dokkum & van der Marel (2006, hereafter vDvdM06), we presented spectroscopy with the Low Resolution Imager and Spectrograph (LRIS) on Keck of some two dozen galaxies in the intermediate-redshift ($z
\approx 0.5$) clusters CL3C295, CL0016+16 and CL1601+42. The sample galaxies were selected to be bright enough for spectroscopy, and visually classified from the Hubble Space Telescope (HST) images of Dressler [[et al. ]{}]{}(1997) and Smail [[et al. ]{}]{}(1997) as early-type (and in most cases elliptical) galaxies. We measured the integrated velocity dispersions of the galaxies and analyzed existing HST images to infer their characteristic photometric properties. This allowed a study of the FP evolution of the three sample clusters. We combined our new results with existing FP data for eleven additional clusters in the redshift range $0.18 \leq z \leq 1.28$ as well as samples of field early-type galaxies in the redshift range $0.32 \leq z \leq
1.14$. This provides the largest homogenized analysis of FP evolution to date and implies a luminosity-weighted mean star formation redshift $z_{*} = 2.01_{-0.17}^{+0.22}$ for massive ($M > 10^{11} {\>{\rm M_{\odot}}}$) early-type galaxies in clusters. Field early-type galaxies in the same
