Рассмотрен и сделан анализ научных открытий и изобретений Ли де Фореста, которые оставили заметный след в радиоламповых технологиях и социуме. Описана борьба де Фореста за приоритет в открытии обратной связи в усилителе звуковой частоты. Отмечено первенство де Фореста в записи звука на кинопленку на основе изобретенной им технологии Phonofilm. Показано, как в драматической жизни де Фореста нашлось место не только занятиям научными исследованиями, но и любви к женщинам.

The scientific discoveries and inventions of Lee de Forest, which left a noticeable mark in radio tube technologies and society, are considered and analyzed. De Forest’s struggle for priority in opening feedback in an audio frequency amplifier is described. The superiority of de Forest in recording sound on film based on the Phonofilm technology invented by him was noted. It is shown how in the dramatic life of de Forest there was a place not only for scientific research, but also for love for women.
