William Dwight Whitney
William Dwight Whitney (; February 9, 1827June 7, 1894) was an American linguist, philologist, and lexicographer known for his work on Sanskrit grammar and Vedic philology as well as his influential view of language as a social institution. He was the first president of the American Philological Association and editor-in-chief of The Century Dictionary.

Life
William Dwight Whitney was born in Northampton, Massachusetts on February 9, 1827. His father was Josiah Dwight Whitney (1786–1869) of the New England Dwight family. His mother was Sarah Williston (1800–1833) of Easthampton, Massachusetts.

He entered Williams College at fifteen, graduating in 1845. He continued studying and worked at a bank in Northampton for several years. He was at first interested in natural sciences, and assisted his older brother Josiah Whitney on a geological survey of the Lake Superior region in 1849, having charge of the botany, the barometrical observations and the accounts. On this expedition, he began the study of Sanskrit in his leisure hours. Around this time Whitney was living at Yale University in Connecticut. In 1850 he then left the United States to study philology, and especially Sanskrit, in Germany. There, he spent his winters at Berlin studying under Franz Bopp and Albrecht Weber, and his summers were devoted to research under Rudolph von Roth at Tübingen. It was during his time in Germany that Whitney began a major life project, "preparation of an edition and translation of the Atharva-veda."

He gained wide reputation for his scholarship in the field. In 1853, Yale University offered Whitney a position as "Professor of Sanskrit", a position made just for him and the first of its kind in the United States. It was not until 1861, however, that he received his doctoral degree from the University of Breslau. He also taught modern languages at the Sheffield Scientific School, and served as secretary to the American Oriental Society from 1857 until he became its president in 1884.

On August 28, 1856 he married Elizabeth Wooster Baldwin. She was the daughter of Roger Sherman Baldwin, US Senator and Governor of the State of Connecticut.
They had six children:
 Edward Baldwin Whitney was born August 16, 1857, became Assistant US Attorney General, and had son mathematician Hassler Whitney.
Williston Clapp Whitney was born April 2, 1859 but died March 11, 1861.
 Marian Parker Whitney was born February 6, 1861, became a professor of German at Vassar College and trustee of Connecticut College for Women
 Roger Sherman Baldwin Whitney was born January 6, 1863, but died January 17, 1874.
 Emily Henrietta Whitney was born August 29, 1864.
 Margaret Dwight Whitney was born November 19, 1866.

He died at his home, on Whitney Avenue, on June 7, 1894.

Career
Whitney revised definitions for the 1864 edition of Webster's American Dictionary, and in 1869 became a founder and first president of the American Philological Association. In the same year he also became Yale's professor of comparative philology. Whitney also gave instruction in French and German in the college until 1867, and in the Sheffield scientific school until 1886. He wrote metrical translations of the Vedas, and numerous papers on the Vedas and linguistics, many of which were collected in the Oriental and Linguistic Studies series (1872–74).  He wrote several books on language, and grammar textbooks of English, French, German, and Sanskrit.

His Sanskrit Grammar (1879) is notable in part for the criticism it contains of the Ashtadhyayi, the Sanskrit grammar attributed to Panini. Whitney describes the Ashtadhyayi as "containing the facts of the language cast into the highly artful and difficult form of about four thousand algebraic-like rules (in the statement and arrangement of which brevity alone is had in view at the cost of distinctness and unambiguousness)."

In his Course in General Linguistics in the chapter on the 'Immutability and Mutability of the Sign', Ferdinand de Saussure credits Whitney with insisting on the arbitrary nature of the linguistic signs.

The linguist Roman Jakobson (Jakobson 1965, 23-4) remarks that Whitney exerted a deep influence on European linguistic thought by promoting the thesis of language as a social institution. In his fundamental books of the 1860s and 70's, language was defined as a system of arbitrary and conventional signs. This doctrine was borrowed and expanded by Ferdinand de Saussure, and it entered into the posthumous edition of his 'Course', adjusted by his disciples C. Bally and Albert Sechehaye (1916). The teacher declares: "On the essential  point  it  seems to  us that  the American linguist  is right: language is a convention, and the nature of the sign that is agreed upon remains indifferent." Jakobson writes, Arbitrariness is posited as the first of two basic principles for defining the nature of the verbal sign: "The bond uniting the signifier with the signified is arbitrary." The commentary points out that no one has controverted this principle "but it is often easier to discover a truth than to assign to it the appropriate place." 

Although he suffered from a heart ailment in his later years, he was editor-in-chief of the first edition of the respected Century Dictionary, which appeared from 1889 to 1891.
