<B>Lee De Forest Signature</B></I> on card 5" x 2", mounted on stiff card stock. De Forest (1873-1961) was an American inventor with over 300 patents to his credit. De Forest invented the Audion, a vacuum tube that takes relatively weak electrical signals and amplifies them. De Forest is one of the fathers of the "electronic age", as the Audion helped to usher in the widespread use of electronics. He was involved in several patent lawsuits and he spent a fortune from his inventions on the legal bills. He had four marriages and several failed companies, he was defrauded by business partners, and he was once indicted for mail fraud, but was later acquitted.
