Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971) was an American inventor and television pioneer. Although he made many contributions that were crucial to the early development of all-electronic television, he is perhaps best known for inventing the first fully functional all-electronic image pickup device (video camera tube), the "image dissector", the first fully functional and complete all-electronic television system, and for being the first person to demonstrate such a system to the public. Farnsworth developed a television system complete with receiver and camera, which he produced commercially in the form of the Farnsworth Television and Radio Corporation, from 1938 to 1951.

In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth–Hirsch fusor, or simply "fusor", employing inertial electrostatic confinement (IEC). Although not a practical device for generating nuclear energy, the fusor serves as a viable source of neutrons. The design of this device has been the acknowledged inspiration for other fusion approaches including the Polywell reactor concept in terms of a general approach to fusion design. Farnsworth held 165 patents, mostly in radio and television.

Philo (20 BCE – 50 CE), known also as Philo of Alexandria (Greek: Φίλων ὁ Ἀλεξανδρεύς), Philo Judaeus, Philo Judaeus of Alexandria, Yedidia, "Philon", and Philo the Jew, was a Hellenistic Jewish Biblical philosopher born in Alexandria.

Philo used philosophical allegory to attempt to fuse and harmonize Greek philosophy with Jewish philosophy. His method followed the practices of both Jewish exegesis and Stoic philosophy. His allegorical exegesis was important for several Christian Church Fathers, but he has barely any reception history within Judaism. "The sophists of literalness," as he calls the literalist Jews, "opened their eyes superciliously" when he explained to them the marvels of his exegesis. He believed that literal interpretations of the Hebrew Bible would stifle mankind's view and perception of a God too complex and marvelous to be understood in literal human terms.

Some scholars hold that his concept of the Logos as God's creative principle influenced early Christology. Other scholars, however, deny direct influence but say both Philo and Early Christianity borrow from a common source. For Philo, the Logos was God's "blueprint for the world", a governing plan.

Joseph Frank "Buster" Keaton (October 4, 1895 – February 1, 1966) was an American comic actor, filmmaker, producer and writer. He was best known for his silent films, in which his trademark was physical comedy with a consistently stoic, deadpan expression, earning him the nickname "The Great Stone Face".

Buster Keaton (his lifelong stage name) was recognized as the seventh-greatest director of all time by Entertainment Weekly. In 1999, the American Film Institute ranked Keaton the 21st-greatest male star of all time. Critic Roger Ebert wrote of Keaton's "extraordinary period from 1920 to 1929, [when] he worked without interruption on a series of films that make him, arguably, the greatest actor-director in the history of the movies."

Orson Welles stated that Keaton's The General is "the greatest comedy ever made, the greatest Civil War film ever made, and perhaps the greatest film ever made."

A 2002 worldwide poll by Sight & Sound ranked Keaton's The General as the 15th best film of all time. Three other Keaton films received votes in the magazine's survey: Our Hospitality, Sherlock, Jr., and The Navigator.

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.

David Sarnoff (Belarusian: Даві́д Сарно́ў, Russian: Дави́д Сарно́в, February 27, 1891 – December 12, 1971) was an American businessman and pioneer of American commercial radio and television. Throughout most of his career he led the Radio Corporation of America (RCA) in various capacities from shortly after its founding in 1919 until his retirement in 1970.

He ruled over an ever-growing telecommunications and consumer electronics empire that included both RCA and NBC, and became one of the largest companies in the world. Named a Reserve Brigadier General of the Signal Corps in 1945, Sarnoff thereafter was widely known as "The General."

Sarnoff is credited with Sarnoff's law, which states that the value of a broadcast network is proportional to the number of viewers.

David Sarnoff was born in Uzlyany, a small town in Belarus, to Abraham and Leah Sarnoff. He emigrated to the United States and raised funds to bring the family. Sarnoff spent much of his early childhood in a cheder studying and memorizing the Torah. He immigrated with his mother and three brothers and one sister to New York City in 1900, where he helped support his family by selling newspapers before and after his classes at the Educational Alliance. In 1906 his father became incapacitated by tuberculosis, and at age 15 Sarnoff went to work to support the family. He had planned to pursue a full-time career in the newspaper business, but a chance encounter led to a position as an office boy at the Commercial Cable Company. When his superior refused him unpaid leave for Rosh Hashanah, he joined the Marconi Wireless Telegraph Company of America on September 30, 1906, and started a career of over sixty years in electronic communications.
