Junction Grammar was pioneered by Eldon Lytle during the 1960's as he studied for his Ph.D. degree in Linguistics from the University of Illinois at Urbana-Champaign. Dr. Lytle believed that the linguistic theories that were dominant at the time were inadequate in their ability to describe natural language in a complete and simple manner.
Beginning in the 1950's, revolutionary linguistic theories began to be developed that borrowed many concepts from the field of formal languages from mathematics and computer science. These theories for the first time showed how language could be generated from sets of rules, which was a major step forward. For many years, any model of language that made different assumptions than the dominant Transformation Generative Grammar (TGG or TG) theory was considered “out of the mainsteam of linguistic thought” and its proponents found it very difficult to even publish their research results. Even today, with many variations of linguistic ideas now flourishing, all of the best known theories still rely heavily on a foundation of formal language theory.
