The story of the word

French coined aéronaute in 1784, months after the Montgolfier brothers had put men into the sky over Paris and nobody had a word for them. The model was ἀργοναύτης, the crew of the Argo, so the first balloonists were framed as sailors on a new sea. Astronaut, cosmonaut and taikonaut all descend from that single balloon-season improvisation.
