... We present color-magnitude diagrams (CMDs) derived from HST WFPC images in the F555W and F785LP filters of the post-starburst galaxy NGC 1569 and we discuss its star formation history. ... To discuss the star formation in NGC 1569, we superpose on the CMD the whole galaxy (see Fig.1) the isochrones calculated by Fagotto et al. (1994) for Z=0.004 as appropriate, since Dufour et al. (1982) and Hunter et al. (1982) derive for NGC 1569 a metal content in between those found for the LMC and the SMC. ...
