Question: Who was the linguist who expanded on languages initially developed by the author of "The Hobbit"?

Context paragraphs:
Typhoon Nelson (1982): Typhoon Nelson, known in the Philippines as Typhoon Bising, was the second tropical cyclone to strike the Philippines within a week in March 1982.  Nelson originated from a tropical disturbance southeast of Guam towards the middle of March.  Although the system was initially poorly organized, it developed rather quickly, and was upgraded into Tropical Storm Nelson on March 19.  It tracked westward, and fluctuated in intensity for several days.  On March 24, Typhoon Nelson intensified into a typhoon, and entered an episode of rapid intensification.  On March 25, Nelson reached its peak intensity of 115 km/h , but thereafter moved ashore on the Philippines, where the storm weakened significantly.  On March 27, the typhoon entered the South China Sea, and the next day, briefly re-intensified before resuming a weakening trend.  Nelson dissipated on March 31.  Affecting the nation less than a week after Tropical Storm Mamie did, Nelson was responsible for additional flooding across much of the Philippines.  Fifty-six people were killed due to the typhoon, eight of whom perished due to drownings.  Over 1,200 homes were destroyed.  More than 165,000 people fled to shelters, including 83,000 that were displaced from their home.  Thirty fishing boats and 23 ferries were destroyed due to the system.  Damage amounted to $17.2 million (1982 USD).

Glycorandomization: Glycorandomization, is a drug discovery and drug development technology platform to enable the rapid diversification of bioactive small molecules, drug leads and/or approved drugs through the attachment of sugars.  Initially developed as a facile method to manipulate carbohydrate substitutions of naturally occurring glycosides to afford the corresponding differentially glycosylated natural product libraries, glycorandomization applications have expanded to include both small molecules (drug leads and approved drugs) and even macromolecules (proteins).  Also referred to as 'glycodiversification', glycorandomization has led to the discovery of new glycoside analogs which display improvements in potency, selectivity and/or ADMET as compared to the parent molecule.

Michael Patrick O'Connor: Michael Patrick O'Connor (1950, Lackawanna, New York – June 16, 2007, Silver Springs, New York) was an American linguist.  O'Connor was a leading linguist in the field of Semitic languages, especially Hebrew.  He had an alternate explanations for Hebrew Bible language which focused on its poetic characters, and expanded the study of the grammar of early Aramaic and other Northwest Semitic dialects.

Slavic vocabulary: The following list is a comparison of basic Proto-Slavic vocabulary and the corresponding reflexes in the modern languages, for assistance in understanding the discussion in Proto-Slavic and History of the Slavic languages.  The word list is based on the Swadesh word list, developed by the linguist Morris Swadesh, a tool to study the evolution of languages via comparison, containing a set of 207 basic words which can be found in every language and are rarely borrowed.  However, the words given as the modern versions are "not" necessarily the normal words with the given meaning in the various modern languages, but the words directly descended from the corresponding Proto-Slavic word (the "reflex").  The list here is given both in the orthography of each language, with accent marks added as necessary to aid in pronunciation and Proto-Slavic reconstruction.  See below for a capsule summary of how to pronounce each language, as well as some discussion of the conventions used.

J. R. R. Tolkien: John Ronald Reuel Tolkien, ( ; 3 January 1892 – 2 September 1973) was an English writer, poet, philologist, and university professor who is best known as the author of the classic high-fantasy works "The Hobbit", "The Lord of the Rings", and "The Silmarillion".

David Salo: David I. Salo is a linguist who worked on the languages of J. R. R. Tolkien for the "Lord of the Rings" film trilogy, expanding the Elvish languages (particularly Sindarin) by building on vocabulary already known from published works, and defining some languages that previously had a very small published vocabulary.  In 2003, he was a graduate student in linguistics at the University of Wisconsin–Madison.

John Lynch (linguist): John Lynch, born 8 July 1946, in Sydney, Australia, is a linguist specializing in Oceanic languages.  He is an emeritus professor of Pacific Languages and the former Director of the Pacific Languages Unit at the University of the South Pacific in Port Vila, Vanuatu.  Prior to moving to Vanuatu, he served the University of Papua New Guinea for 21 years, the last five as Vice-Chancellor.  His areas of focus are languages of Vanuatu; history of languages of the Pacific; pidgin and creole languages; language change; dictionaries; orthography design.  He is currently the editor of the journal "Oceanic Linguistics".

Apache Hive: Apache Hive is a data warehouse software project built on top of Apache Hadoop for providing data summarization, query, and analysis.  Hive gives an SQL-like interface to query data stored in various databases and file systems that integrate with Hadoop.  Traditional SQL queries must be implemented in the MapReduce Java API to execute SQL applications and queries over distributed data.  Hive provides the necessary SQL abstraction to integrate SQL-like queries (HiveQL) into the underlying Java without the need to implement queries in the low-level Java API.  Since most data warehousing applications work with SQL-based querying languages, Hive aids portability of SQL-based applications to Hadoop.  While initially developed by Facebook, Apache Hive is used and developed by other companies such as Netflix and the Financial Industry Regulatory Authority (FINRA).  Amazon maintains a software fork of Apache Hive included in Amazon Elastic MapReduce on Amazon Web Services.

Transcendental realism: Initially developed by Roy Bhaskar in his book "A Realist Theory of Science" (1975), transcendental realism is a philosophy of science that was initially developed as an argument against epistemic realism of Positivism and Hermeneutics.  The position is based on Bhaskar's transcendental arguments for certain ontological and epistemological positions based on what reality must be like in order for scientific knowledge to be possible.  While Bhaskar's work is the origin of transcendental realism, it is based upon and further developed by a number of other authors[ref: Collier, Sayer, Lawson, Critical Realism: Essential Readings, etc.  The overview of transcendental realism that follows is largely based on Andrew Sayer's "Realism and Social Science".

Muted group theory: Muted group theory (MGT) is developed by social anthropologists Edwin Ardener and Shirley Ardener in 1975.  The theory describes the relationship between a dominant group and its subordinate group(s): As the dominant group contributes mostly to the formulation of the language system, including the norms and vocabulary, members from the subordinate group have to learn and use the dominant-made language to express themselves.  However, this translation process may result in loss and distortion of information as the people from subordinate groups cannot articulate their ideas clearly.  The dominant may also ignore the voice of the lower-power.  All these may eventually lead to the mutedness of the subordinate group.  Although this theory is initially developed to study the different situations faced by women and men, it can also be applied to any marginalized group that is muted by the inadequacies of their languages.
