Book excerpt: We present a measurement of the[ital b] quark fragmentation function from a sample of semi-leptonic[bold B] decays collected between 1993 and 1995 in the SLD experiment at SLAC. The energy of each tagged[bold B] hadron was reconstructed using information from the lepton and a partially reconstructed charm decay vertex. A comparison of the scaled energy distribution with several phenomenological models of heavy quark fragmentation was made, using the same model in each case to correct the data. The average scaled energy was found to be[l-angle][chi][sub E][r-angle]= 0.697[+-]0.012([ital stat])[sup+0. 028][sub -0.024] ([ital syst])(preliminary).
