A measurement of the average lifetime of hadrons containing bottom quarks is presented. The b-hadrons are produced in e+e-annihilation at 29 GeV, and the lifetime is determined from the impact parameters of high transverse momentum electrons produced in the decay of the b-hadrons. A b-lifetime of rb = 1.17+~:$ (stat.) Tz:$ (sys.) psec is determined from a maximum likelihood fit to the impact parameters. Particular care has been taken to describe the experimental resolution correctly in the fit.
