The term

Before we discuss how Ansible started, we should quickly discuss the origin of the name. The term Ansible was penned by science fiction novelist Ursula K. Le Guin; it was first used in her novel Rocannon's World, first published in 1966. In the context of the story, an Ansible is a fictional device that is able to send and receive messages faster than light.

In 1974, Ursula K. Le Guin's novel The Dispossessed: An Ambiguous Utopia, was published; this book features the development of the Ansible technology by exploring the (fictional) details of the mathematical theory that would make such a device possible.

The term has since been used by several other notable authors within the genre to describe communication devices that are capable of relaying messages over interstellar distances.
