title: Examples of electrostatic electron optics: the Farrand and Elektros microscopes and electron mirrors.
abstract: The role of Gertrude Rempfer in the design of the Farrand and Elektros microscopes is evoked. The study of electron mirror optics, aberration correction using mirrors and the development of microscopes employing electron mirrors are recapitulated, accompanied by a full bibliography, of earlier publications in particular.
