The earliest known appearance of the phrase is from The Michigan School Moderator, a journal that provided teachers with education-related news and suggestions for lessons.^[1] In an article titled "Interesting Notes" in the March 14, 1885 issue, the phrase is given as a suggestion for

writing practice: "The following sentence makes a good copy for practice, as it contains every letter of the alphabet: 'A quick brown fox jumps over the lazy dog.'"^[2] Note that the phrase in this case begins with the word "A" rather than "The". Several other early sources also use this variation.

As the use of typewriters grew in the late 19th century, the phrase began appearing in typing and stenography lesson books as a practice sentence. Early examples of publications which utilized the phrase include Illustrative Shorthand by Linda Bronson (1888),^[3] How to Become Expert in Typewriting: A Complete Instructor Designed Especially for the Remington

Typewriter (1890),^[4] and Typewriting Instructor and Stenographer's Hand-book (1892). By the turn of the 20th century, the phrase had become widely known. In the January 10, 1903, issue of Pitman's Phonetic Journal, it is referred to as "the well known memorized typing line embracing all the letters of the alphabet".^[5] Robert Baden-Powell's book Scouting for Boys (1908) uses the phrase as a practice sentence for signalling.^[6]
