The elemental abundances of the Crab Nebula are compared with the presupernova models of 8–12 M⊙ stars. The small carbon abundance of the Crab is consistent with only the star whose main-sequence mass was 8–9.5 M⊙. More massive stars contain too much carbon in the helium layer and smaller mass stars do not leave neutron stars. A scenario for the Crab Nebula's progenitor is proposed.
