The discovery of 10 active galactic nuclei (AGNs) based upon optical observations of Einstein Observatory X-ray sources is reported. The new objects are optically similar to AGNs that have been identified by others with this technique. One notable exception, the quasar E1821 + 643, is associated with a previously unidentified X-ray source detected with both the low-energy and high-energy surveys of the HEAO 1 A-2 experiment. It is thus one of a small number of AGNs which were more intense in soft X-rays than in hard X-rays during 1977-1978. X-rays were also detected from two other quasars, known previously at other wavelengths.
