Eliza is the name of a 1966 invention by German born scientist, Joseph Weizenbaum, that is said to be the first chatbot.
Eliza worked by someone typing their feelings into a computer keyboard, and then the programme repeated it back to them, often as a question.
Joseph’s daughter, Miriam tells Gill Kearsley about Eliza. We also hear from Joseph through archive interviews from Carnegie Mellon University in Pittsburgh, in the USA, that were recorded with Pamela McCorduck in 1975.
