Andrew V. Haeff: Enigma of the Tube Era and Forgotten Computing Pioneer

Prolific, yet neglected inventor Andrew Vasily Haeff (1905-1990) made numerous contributions to vacuum tube art, including the traveling wave tube, the inductive-output tube, the electron-wave tube (or "double-stream" amplifier), the resistive wall tube, and many others. Haeff's contributions to computing history include his pioneering computer monitor technology, his high-speed electrostatic computer memory tube, and his early work in the display and storage of text and graphics.
