We present a study of white dwarfs that are in common proper motion with bright Hipparcos stars. The parallax measurement of the Hipparcos companion allows to obtain an accurate mass estimate of each white dwarf. In addition, since the stars are distant companions they would have evolved without any interaction, providing us with additional constraints on the evolution of single stars and, in particular, on the the initial-to-final mass relations.
