EZ Word, a word processor that is part of the Andrew User Interface System, was the first graphical word processor available for Linux. It was part of a user-interface research project jointly done by both IBM and the Carnegie Mellon University.
Many people found the user interface quirky and difficult to learn. The program never really caught on, and the Andrew project stopped developing software in 1997. The last version of the AUIS suite, version 8.0, was never fully debugged, but is free software available under a BSD license.
