William Strunk Jr. (1 July 1869 26 September 1946) was a professor of English at Cornell University and author of the The Elements of Style (1918), which, after being revised and enlarged by his former student E. B. White, became a highly influential guide to English usage during the late 20th century.Strunk was born and reared in Cincinnati, Ohio, the eldest of four surviving children of William and Ella Garretson Strunk. He earned a bachelor’s degree at the University of Cincinnati in 1890 and a PhD at Cornell University in 1896. He spent the academic year 1898 99 at the Sorbonne and the Collège de France, where he studied morphology and philology.

Strunk first taught mathematics at Rose Polytechnical Institute in Terre Haute, Indiana in 1890 91. He then taught English at Cornell for 46 years, disdaining specialization and becoming expert in both classical and non-English literature. In 1922 he published English Metres, a study of poetic metrical form, and he compiled critical editions of Cynewulf’s Juliana, several works of Dryden, James Fenimore Cooper’s Last of the Mohicans, and several Shakespearean plays. Strunk was also active in a gathering known as the Manuscript Club., an “informal Saturday-night gathering of students and professors interested in writing,” where he met Elwyn Brooks White.

In 1935 36, Strunk enjoyed serving as the literary consultant for the Metro-Goldwyn-Mayer film Romeo and Juliet (1936).

In 1918, Strunk privately published The Elements of Style for the use of his Cornell students, who gave it its nickname, “the little book.” Strunk intended the guide “to lighten the task of instructor and student by concentrating attention…on a few essentials, the rules of usage and principles of composition most commonly violated. In 1935, Strunk and Edward A. Tenney revised and published the guide as The Elements and Practice of Composition (1935).

In his New Yorker column of July 27, 1957, E. B. White praised the “little book” as a “forty-three-page summation of the case for cleanliness, accuracy, and brevity in the use of English.” Macmillan and Company then commissioned White to revise The Elements of Style for republication. White’s expansion and modernization of the 1935 edition sold more than two million copies. Since 1959, total sales of three editions in four decades has exceeded ten million copies.
