This paper discusses electron-positron annihilation at high energy. This work began in 1977 with the DASP II Collaboration at the DORIS storage ring of the DESY Laboratory in Hamburg. The collaboration's first publication reported the observation of the narrow {Upsilon} resonance at 9.46 GeV, confirming the original observation of this state in proton-nucleus collisions at Fermilab. To enable investigations of the {Upsilon} family of resonances the DORIS ring was rebuilt for reliable operation at the top of its energy range where the {Upsilon} states are accessible. In addition a new detector, ARGUS, was installed at one interaction region. This paper also discusses the AMY Collaboration which investigates electron-positron annihilation at energies from 50 to 65 GeV. The AMY detector is in the beam of the TRISTAN collider of the KEK Laboratory in Tsukuba, Japan.
