After three years of data taking, the four LEP experiments collected a total of about four million Z{sup 0} hadronic decays, in which a heavy quark pair (either b{bar b} or c{bar c}) is produced with 40% probability. Results are presented both in the sector of the electroweak precision measurements, with particular emphasis on the beauty quark, and in the determination of the beauty decay properties, where lifetimes and branching ratio measurements take advantage of the large statistics now available and of the recent improvements in the analysis based on microvertex detectors and particle identification devices.
