Theodor Holm Nelson (Ted Nelson, born 1937) is an American sociologist, philosopher, and pioneer of information technology. He coined the terms "hypertext" and "hypermedia" in 1963 and published it in 1965. He also is credited with first use of the words "transclusion", "virtuality", "intertwingularity" and "teledildonics". The main thrust of his work has been to make computers easily accessible to ordinary people. His motto is: "A user interface should be so simple that a beginner in an emergency can understand it within ten seconds." However, he is known for inventing many new words (neologisms) which few other people understand (such as "intertwingularity"), and his remarks contain humor to entertain rather than just inform. Consequently, some of his ideas have been met with negative reactions.
