Spectroscopy of the individual stellar components in four compact OB multiple systems of the LMC, previously imaged with the HST-WFPCS, has been performed with the HST-FOS. In every case, the uncontaminated spectra of the WR and/or Of-type components have been observed for the first time. The spectra of the normal OB companions provide information about the initial masses and ages of the peculiar objects. Several additional evolved and peculiar objects within these systems have also been discovered.
