Abstract:	We measure the luminosity function of morphologically selected E/S0 galaxies from $z=0.5$ to $z=1.0$ using deep high resolution Advanced Camera for Surveys imaging data. Our analysis covers an area of $48Boxarcmin$ (8$ imes$ the area of the HDF-N) and extends 2 magnitudes deeper ($Isim24$ mag) than was possible in the Deep Groth Strip Survey (DGSS). At $0.51.7$, E/S0 galaxies at brighter luminosities ($M_B<-20.1$), but are increasingly different at fainter magnitudes where `blue’ galaxies are both smaller and have lower Sersic parameters. Fits of the colors to stellar population models suggest that most E/S0 galaxies have short star-formation time scales ($ au<1$ Gyr), and that galaxies have formed at an increasing rate from $zsim8$ until $zsim2$ after which there has been a gradual decline.
