Combining optical and UV imaging with spectroscopy of member galaxies, we identify and study several key classes of "transition objects" whose stellar populations or dynamical states indicate a recent change in morphology and star formation rate. For the first time, we have been able to conclusively identify spiral galaxies in the process of transforming into S0 galaxies. This has been accomplished by locating both spirals whose star formation is being quenched and their eventual successors, the recently created S0s. Description: We make use of HST imaging of Cl 0024 and MS 0451 from the comprehensive wide-field survey described in Paper I (Treu et al., Cat. J/ApJ/591/53) and G.P. Smith et al. (2008, in preparation). Cl 0024 and MS 0451 were observed for 15 and 80ks, respectively, with GALEX in 2004 October (GO-22; Cycle 1; PI: Treu), reaching comparable depths in rest-frame far-ultraviolet (FUV) (observed near-ultraviolet [NUV]). We have used DEIMOS on Keck II to obtain deep spectra of ∼1500 galaxies per cluster in the fields of Cl 0024 and MS 0451. Observations of Cl 0024 from 2001 October to 2003 October are described in Papers I (Treu et al., Cat. J/ApJ/591/53) and III (Moran et al., Cat. J/ApJ/634/977). We undertook an initial redshift survey of MS 0451 during 2003 October. We have additionally observed both clusters again in 2004 December and 2005 October.
