"an American literary magazine edited by Scofield Thayer"

Massachusetts-born Scofield Thayer (1889-1982) was both editor of The Dial and a prominent art collector -- his collection is now housed at the Metropolitan Museum of Art.  

The Dial was initially launched in connection with the Transcendentalists in 1840, undergoing a revival in the 1880s as a political publication. However, it was not until 1920 -- under the editorship of both Thayer and Dr. James Sibley Watson Jr. -- that the periodical would be revived as a literary journal. Thayer and Watson created the $2,000 Dial Award in 1921. Publication of the magazine ceased in 1929.
