Question: Which Russian linguist and historian whose teachings formed a nucleus of the Prague School of structural linguistics published in Michigan Slavic Publications founded by Ladislav Matejka?
Context: Jan Firbas (25 March 1921 in Brno – 5 May 2000 in Brno), was a Czech linguist and a prominent representative of the Prague School of linguistics.  Born in Brno, in the Czech Republic, he studied English, German and philosophy at the Faculty of Arts of Masaryk University.  From 1949 he was a member of the Department of English and American Studies of the faculty until his death in 2000.  He became a member of the Prague Linguistics Circle, which was outlawed by the communist government.  Persecution from the communist government and the fact that he came from an old Protestant family and refused to renounce his belief significantly delayed his academic career.  Despite his international renown, it took him ten years to have his habilitation officially approved and he was only made Professor in 1990.  In 1986, he was awarded Honorary Doctorates by the Universities of Leuven and Leeds, and in 2000 by the University of Turku.  Even though he was frequently invited to give lecture series at universities across the globe in the 1970s and 80s, he could freely accept the invitations only after the fall of the communist regime in November 1989.  Jan Firbas died on 5 May 2000 in Brno, the city where he had stayed for most of his life. Ladislav Matějka (May 30, 1919 in České Budějovice – September 29, 2012 in West Newton, Massachusetts) was a Czech scholar of semiotics and linguistic theory, who translated and published many contributions to Prague linguistic circle theory.  He received his doctorate in Charles University in Prague in 1948 and then emigrated to the U.S. From 1956 until 1989 he taught at University of Michigan in the Slavic Department.  In 1962, he founded Michigan Slavic Publications, a series that has published more than 100 volumes by authors such as Roman Jakobson and Nikolai Trubetzkoy. Aleš Svoboda (2 April 1941 in Zlín – 9 January 2010 in Opava), was a Czech linguist and a prominent representative of the Prague School of linguistics.  His early interests lead him to study music and clarinet play at Brno conservatoire, but later it was a keen interest in languages which brought him to study English, German and Czech at the Faculty of Arts of Masaryk University.  In 1970 he became an Assistant Professor of the Department of English and American Studies at the faculty.  He was promoted to the rank of Associate Professor at Charles University in Prague in 1981 and to Full Professor at Masaryk University in Brno in 1992.  Apart from Masaryk University in Brno, he also taught at Silesian University in Opava and at the University of Ostrava (both in the Czech Republic), and at University of Prešov (Slovakia). Prince Nikolai Sergeyevich Trubetzkoy (also Troubetskoy; Russian: Никола́й Серге́евич Трубецко́й; Moscow, April 16, 1890 – Vienna, June 25, 1938) was a Russian linguist and historian whose teachings formed a nucleus of the Prague School of structural linguistics.  He is widely considered to be the founder of morphophonology.  He was also associated with the Russian Eurasianists. Leonard Bloomfield (April 1, 1887 – April 18, 1949) was an American linguist who led the development of structural linguistics in the United States during the 1930s and the 1940s.  His influential textbook "Language", published in 1933, presented a comprehensive description of American structural linguistics.  He made significant contributions to Indo-European historical linguistics, the description of Austronesian languages, and description of languages of the Algonquian family. In linguistics, Functional Sentence Perspective (FSP) is a theory describing the information structure of the sentence and language communication in general.  It has been developed in the tradition of the Prague School of Functional and Structural Linguistics together with its sister theory, Topic-Focus Articulation. The Annual Workshop on Formal Approaches to Slavic Linguistics (often abbreviated FASL) is one of the most reputable international academic conferences in the field of formal Slavic linguistics.  Each meeting is hosted by a United States or Canada university in May; the proceedings are published in the next year by Michigan Slavic Publishers of University of Michigan in Ann Arbor, MI. László Antal (Szob, Hungary, 25 June 1930 – Washington, January 1993) was a Hungarian linguist, structuralist, Doctor of Science (1981), and Professor of Linguistics.  He was considered the sole representative of structural linguistics in America in Hungary.  He adapted American structuralism to the Hungarian language.  He was a lone wolf in Hungarian linguistics. Structural linguistics is an approach to linguistics originating from the work of Swiss linguist Ferdinand de Saussure and is part of the overall approach of structuralism.  Structural linguistics involves collecting a corpus of utterances and then attempting to classify all of the elements of the corpus at their different linguistic levels: the phonemes, morphemes, lexical categories, noun phrases, verb phrases, and sentence types. The Copenhagen School, officially the Linguistic Circle of Copenhagen (French: "Cercle Linguistique de Copenhague"), is a group of scholars dedicated to the study of linguistics.  It was founded by Louis Hjelmslev (1899–1965) and Viggo Brøndal (1887–1942).  In the mid twentieth century the Copenhagen school was one of the most important centres of linguistic structuralism together with the Geneva School and the Prague School.  In the late 20th and early 21st century the Copenhagen school has turned from a purely structural approach to linguistics to a functionalist one, Danish functional grammar, which nonetheless incorporates many insights from the founders.
