摘要：

We present the result of near-infrared spectroscopic observations of the radio galaxy 3C 22 (z = 0.937). Contrary to the previous classification of this object as a narrowline radio galaxy, we report the clear presence of a broad H alpha line, showing directly that at least some powerful radio galaxies are simply reddened quasars.
