The prints of the Palomar Sky Survey, luminosity classificaiton and radialvelocities were used to assign all northern Shapley-Ames galaxies to either (1)field, (2) group, or (3) cluster environments. This information for 930galaxies shows no evidence for a dependence of bar frequency on galaxyenvironment. This suggests that the formation of a bar in a dish galaxy ismainly determined by the properties of the parent galaxy, rather than by thecharacteristics of its environment.Comment: 18 pages. no figures. To be published in the August 2002 issue of the Astronomical Journa
