During an all-sky redshift survey of IRAS galaxies, the authors have discovered a very unusual quasar (IRAS source 07598+6508). The optical spectrum is dominated by extremely strong Fe II emission, roughly an order of magnitude stronger than that seen in so-called strong Fe II emitters. There seems to exist a very small class of super-strong Fe II emitters. Current photo-ionization models do not readily account for the extreme properties of these objects.
