The energy versus time of arrival pattern of neutrinos from SN1987A is sensitive to a neutrino mass, mν, of order a few eV. To disentangle constraints on mν from the data, a theory of supernova emission is necessary. We recall the present status of this theory and approximate its predictions in two diffusion models: one designed to reflect the present supernova lore, the other devised to pessimize, within reason, the consequent upper limits on mν. We discuss the model dependence and statistical significance of our results, as well as the experimental uncertainties and caveats to which they are subject. We address the question, do the supernova results supercede the present laboratory limits on mν?
