We measure the luminosity function of morphologically selected E/S0 galaxiesfrom $z=0.5$ to $z=1.0$ using deep high resolution Advanced Camera for Surveysimaging data. Our analysis covers an area of $48\Box\arcmin$ (8$\times$ thearea of the HDF-N) and extends 2 magnitudes deeper ($I\sim24$ mag) than waspossible 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 thecolors to stellar population models suggest that most E/S0 galaxies have shortstar-formation time scales ($\tau<1$ Gyr), and that galaxies have formed at anincreasing rate from $z\sim8$ until $z\sim2$ after which there has been agradual decline.Comment: 39 pages, 21 figures, accepted in A
