The discovery of a galaxy associated with 3C273 is reported. The QSO 3C273 has some outstanding characteristics. It is the first QSO for which the redshift was determined. It is also the brightest and best studied QSO and its intrinsic luminosity is nearly an order of magnitude greater than that of any other QSO in its redshift range. Some 75 arc sec east of 3C273 a bright galaxy was discovered. Spectroscopic observations of this galaxy, consisting of eight 12-min exposures, were obtained with the photographic image-tube camera mounted on the Cassegrain spectrograph of the Mauna Kea 2.2-meter telescope. The spectrograms were traced with a 12 micrometer square aperture on a microdensitometer and were reduced in a similar manner to that described by Stockton (1976).
