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 (1873–1961) was an inventor, most notably of Audion vacuum tubes in the early twentieth century. His serial business ventures included work in radio, telegraphy, telephony, broadcasting, and film.
