We report a path-integral calculation of the ground state energy of a polaron in a magnetic field. The present calculation is expected to be valid for arbitrary magnetic field strength and arbitrary electron-phonon coupling constant. The effective interaction of the electron with the longitudinal-optical phonons is simulated by an anisotropic Feynman model. For physical values of the coupling constant, energy values have been obtained which are lower than those reported in the literature up to now.
