Observations with a photoelectric interferometer (a simplified version of a speckle interferometer) mounted on a 1-m telescope demonstrate that the bright B stars Zeta, Dra, Omicron Her, and Iota Lyr are binary systems. All three are likely to have short periods. Analysis of the kinematic properties of B stars and their typical spectrum indicates that many of them are probably undiscovered binaries.
