Ursula K. Le Guin
Le Guin created the word "ansible" for an instantaneous interstellar communication device in 1966. Several other writers, including Orson Scott Card and Neil Gaiman, used the word later. The notion that names can exert power is also present in Hayao Miyazaki's 2001 film Spirited Away; critics have suggested that that idea started with Le Guin's Earthsea series.
