During World War I, Wallace enlisted in the U.S. Army and was wounded. He spent four months in a French hospital recovering from his injuries, passing the time by reading American magazines.
Returning to the U.S., Wallace spent every day of the next six months at the Minneapolis Public Library researching and condensing magazine articles. He wanted to create a magazine with articles on a wide variety of subjects, abridged so that each could be easily read. Wallace showed his sample magazine to Lila Bell Acheson, sister of an old college friend, Barclay Acheson,[2][3] who responded enthusiastically. He proposed to her and on October 15, 1921, they were married.
The Wallaces decided to publish the magazine themselves and market it by direct mail. The first issue appeared on February 5, 1922. Reader's Digest soon became one of the most widely circulated periodicals in the world. Wallace was a supporter of the Republican Party with strong anti-communist views, and the magazine reflected these beliefs.[4][5][6] Wallace and his wife were strong supporters of Richard Nixon's presidential bid in 1968, giving Nixon cash donations and allowing Nixon to write articles for the Digest.[7]
