We have completed a blue-green Grism survey for carbon stars in the seven “classical” dwarf spheroidal galaxies. The results for six of them have been published already, while the results for the Fornax galaxy are presented here: this galaxy contains 77 carbon stars, including 30 new objects. The bolometric luminosity function of Fornax is intermediate between that of the Small and of the Large Magellanic Cloud. We will also compare these carbon stars with the fainter objects in the galactic bulge and in the galactic halo and discuss their properties in relation with the metallicity and history of star formation in the parent galaxies.
