Elizabeth Magie (1866–1948), also known as Lizzie Magie, was an American political activist, game designer, and inventor. She was born in Macomb, Illinois, as the daughter of James Magie, a newspaper publisher and abolitionist. According to the provided context, her father was a passionate political thinker who accompanied Abraham Lincoln in political oratory, and he helped shape her critical approach to politics and economics.

Magie was deeply influenced by Henry George’s ideas, especially the Single Tax theory. She worked to spread these ideas through lectures and other forms of public education, but she also recognized the limits of relying only on written argument to reach a wider audience. This led her to create games as a more accessible way to communicate economic criticism.

Her best-known work is The Landlord’s Game, conceived in 1903. The game later became known as the prototype for Monopoly, but its original purpose was educational rather than recreational. It was designed to demonstrate how land ownership and rent monopolies increase inequality. The game included two rule sets: a “monopoly” rule, in which players accumulate land and drive others into bankruptcy, and a “prosperity” rule, in which land value is shared for the benefit of all players. By changing the rules on the same board, Magie showed how systems shape behavior, economics, and ethics.

Magie was also active as a performer and inventor. She worked as a stenographer and typist, wrote poetry and plays, and received a patent in 1893 for an improvement to typewriter paper feeding. In 1906, she staged a provocative newspaper advertisement criticizing women’s economic dependence on marriage. Later, her name was erased from Monopoly’s packaging, and her role as the original creator was largely obscured.
