There has been exciting progress in recent years in the search for a permanent electric dipole moment of atoms, molecules, and the neutron. Such a dipole can exist only if time reversal symmetry is violated. We present a brief survey of the current experiments and results, and summarize what they imply about the size of possible T violating interactions among elementary particles. We conclude with a short description of the latest EDM experiment on mercury atoms at the University of Washington, which sets a new upper bound on the dipole moment, d([sup 199]Hg)[lt]3[times]10[sup [minus]27] ecm.
