Hebrew. Such a grammar would generate the phonetic or sound forms of sentences. To this end, he organized Harris's methods in a different way. To describe sentence forms and structures, he came up with a set of recursive rules. These are rules that refer back to themselves. He also found that there were many different ways of presenting the grammar. He tried to develop a method to measure how simple a grammar is. For this, he looked for "generalizations" among the possible sets of grammatical rules. Chomsky completed his undergraduate thesis The Morphophonemics of Modern Hebrew in 1949. He then published a revised and expanded version of it as his master's thesis in 1951. In 1951, Chomsky became a Junior Fellow at Harvard University. There, he tried to build an all-formal linguistic theory. It was a clear break with the existing tradition of language study. In 1953, Chomsky published his first paper as a scholar. In it he tried to adapt the symbol-based language of logic to describe the syntax of a human language. During his fellowship, Chomsky organized all his ideas into a huge manuscript. It was around 1,000 typewritten pages long. He gave it the title The Logical Structure of Linguistic Theory (LSLT). In 1955, Chomsky found a job at MIT. He worked there as a linguist in the mechanical translation project. The same year he submitted his doctoral dissertation to the University of Pennsylvania. The university granted him a Ph.D. for his thesis Transformational Analysis. In fact, it was just the ninth chapter of LSLT. Publication In 1955, Chomsky had a doctorate in linguistics. Even so, he struggled at first to publish his theory and views on language. He offered the manuscript of The Logical Structure of Linguistic Theory (LSLT) for publication. But MIT's Technology Press refused to publish it. He also saw a paper promptly rejected by the academic linguistics journal WORD. So he remained an outsider to the field of linguistics. His reviews and articles at the time were mostly published in non-linguistic journals. Mouton & Co. was a Dutch publishing house based in The Hague. They had gained academic reputation by publishing works on Slavic Studies since 1954. Particularly, they had published works by linguists Nicolaas Van Wijk and Roman Jakobson. Soon they started a new series called Janua Linguarum or the "Gate of Languages." It was intended to be a series of "small
