Thayer's involvement with
The Dial began in April 1918 when he purchased $600
USD worth of stock in the magazine. In late 1919, Thayer and his fellow Harvard alumnus Dr.
James Sibley Watson, Jr. purchased
The Dial from the owner, Martyn Johnson, who was suffering financial trouble. Dr. Watson became the magazine's president while Thayer took up the post of editor. The new team produced its first issue of
Dial in January 1920. The issue featured works from
E. E. Cummings,
Gaston Lachaise, Arthur Wilson (
Winslow Wilson) and
Carl Sandburg. In July 1921, Thayer sailed for Europe. He settled in
Vienna, and, although he would remain there for more than two years, he continued to direct the operations of
The Dial. He solicited financial backing from European investors and sent layout and content instructions back to the magazine's offices in New York regularly. While in Vienna he was psychoanalysed by
Sigmund Freud. During the mid-1920s Thayer began to suffer a series of mental breakdowns, and began to deteriorate. He resigned as editor of
The Dial in June 1926, and spent the remainder of his life in the care of relatives and various institutions and sanatoria. He was diagnosed with
paranoid schizophrenia. Watson continued with
The Dial, working with editor
Marianne Moore. Their final issue was published in July 1929. Thayer was certified insane in 1937, the year after his mother died. He thenceforth lived the secluded life of a rich man, surrounded by servants, and moving among homes in
Bermuda,
Florida,
Boston, and his family home on
Martha's Vineyard. == Personal life and death ==
