  Surface photometry has been performed on a sample of 46 field elliptical
galaxies. These galaxies are described well by a deVaucouleurs R^{1/4} profile.
The sample was selected from the combined Canada-France and LDSS redshift
surveys and spans the range 0.20 < z < 1.00. The relationship between galaxy
half-light radius and luminosity evolves such that a galaxy of a given size is
more luminous by Delta M_B=-0.97 \pm 0.14 mag at z=0.92 and the mean rest-frame
color shifts blueward by Delta (U-V) =-0.68 \pm 0.11 at z=0.92 relative to the
local cluster relations. Approximately 1/3 of these elliptical galaxies exhibit
[OII] 3727 emission lines with equivalent widths > 15 angstroms indicating
ongoing star formation. Estimated star-formation rates imply that \le 5% of the
stellar mass in the elliptical galaxy population has been formed since z=1. We
see no evidence for a decline in the space density of early-type galaxies with
look-back time. The <V/V_{max}> statistics and a comparison with local
luminosity functions are both consistent with the view that the population of
massive early-type galaxies was largely in place by z~1. This implies that
merging is not required since that time to produce the present-day space
density of elliptical galaxies.
