From the time of their discovery in 1867, Wolf-Rayet stars have been objects of great interest for theoretical astrophysicists. Their spectra, dominated by extremely wide emission lines, set them apart from the run-of-the-mill stars. Moreover, the classic assumptions that have enabled accurate model atmospheres to be constructed for hot main sequence stars: hydrostatic equilibrium, radiative equilibrium, local thermodynamic equilibrium, and negligible curvature effects, are probably all violated in Wolf-Rayet stars. As early as 1894, Scheiner proposed that
