Abstract: Data collected with the High Resolution Spectrometer at PEP, corresponding to an integrated luminosity of 200 pb-1 of e+e- annihilation at 29 GeV, were used to measure the mean lifetime of hadrons containing the bottom quark. The lifetime was determined using the impact parameter method on events containing a high-transverse-momentum electron. The result, based on a sample of 301 events, is [tau]B = 1.02 +/-0.390.42 ps, where the indicated errors include both statistics and systematics.
