Cornell University English professor William Strunk Jr. wrote The Elements of Style in 1918 and privately published it in 1919, for use at the university. Harcourt republished it in 52-page format in 1920.[citation needed] Strunk and editor Edward A. Tenney later revised it for publication as The Elements and Practice of Composition (1935). In 1957, the style guide reached the attention of E.B. White at The New Yorker. White had studied writing under Strunk in 1919 but had since forgotten "the little book" that he described as a "forty-three-page summation of the case for cleanliness, accuracy, and brevity in the use of English." Weeks later, White wrote about Strunk's devotion to lucid English prose in his column.[1][2]
