Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park" (now Edison, New Jersey) by a newspaper reporter, he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory.

Edison is the fourth most prolific inventor in history, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany. He is credited with numerous inventions that contributed to mass communication and, in particular, telecommunications. These included a stock ticker, a mechanical vote recorder, a battery for an electric car, electrical power, recorded music and motion pictures.

Indian giver is an expression used to describe a person who gives a gift (literal or figurative) and later wants it back, or something equivalent in return.

The term "Indian gift" was first noted in 1765 by Thomas Hutchinson, and "Indian giver" was first cited in John Russell Bartlett's Dictionary of Americanisms (1860) as "Indian giver. When an Indian gives any thing, he expects to receive an equivalent, or to have his gift returned." Thus it was really an exchange of gifts and not a matter of selflessness.

The phrase can be considered offensive, particularly to Native Americans.

It is unclear exactly how the expression came to be, but the consensus is that it is based on American Indians having a distinctly different sense of property ownership than people of European ancestry.^{[citation needed]} One theory is that early European settlers in North America misinterpreted the aid and goods they received from local Indians as gifts, when in fact they were intended to be offered in trade. Many tribes operated economically by a form of barter system, or a gift economy, where reciprocal giving was practiced.
