Knowing the mass of the b -quark is essential to the study of the structure and decays of B -mesons as well as to future tests of the Higgs mechanism of mass generation. We present recent preliminary measurements of the b -quark mass and related nonperturbative parameters from moments of kinematic distributions in charmed and charmless semileptonic B -meson decays. Their determination from charmless semileptonic B -meson decays is the first measurement in this mode. The data were collected by the BABAR detector at the PEP-II asymmetric-energy e + e - -collider at the Stanford Linear Accelerator Center at a center-of-mass energy of 10.58GeV.
