The memo outlines the reasons Beckman should not undertake development of Lee de Forest's light amplifier.
This letter suggests Beckman might be interested in commercial development of de Forest's new invention, a "sandwich, non-vacuous, light amplifier."
Lee de Forest states that he has "temporarily become disassociated from the activities of De Forest Television Corporation" and advises Beckman to retain any equipment currently in his possession.
Lee de Forest…
