He joined the staff of The New Republic in 1925. There, literary criticEdmund Wilson encouraged him to write for the magazine. By 1928, he became an assistant editor and by 1929 an associate editor. He joined Time in 1929 as book editor and moved up to assistant managing editor, executive editor, and managing editor. Finally, he succeeded Time co-founder Henry Luce as the magazine's editor, serving in that position from 1949 to 1953. Matthews' relationship with Time soured over the 1952 presidential election. Luce favored Republican nominee Dwight D. Eisenhower but Matthews preferred his Democratic rival Adlai Stevenson II. At Luce's instigation, Matthews moved to England to study a British version of Time. When the project did not carry through, he remained in Britain. There, he wrote numerous books and poetry, including an autobiography and a book on T. S. Eliot. He also reviewed books for the New York Times.
Impact
The New York Times credited Matthews with "bringing depth and refinement to the news weekly in a 25-year career." It described him as a "lean, athletic editor" with "clipped, quiet speech was filled with obscure literary references" who rid the magazine of its double-barreled adjectives, puns and backward sentences." Whittaker Chambers, who started after and ended before Matthews at Time, summarized as follows: "T. S. Matthews' contribution to the humanity of Time, both in the intellectual and personal sense of the word, cannot be overstated." However, W.A. Swanberg, author of the Pulitzer Prize-winning biography Luce and His Empire, criticized Matthews for emphasizing the readability of Time at the expense of objectivity. “For him to be managing editor of America's most politically oriented and propagandist 'newsmagazine' was as if F. Scott Fitzgerald were Secretary of State," Swanberg wrote. Swanberg also characterized Matthews as being “as close to being politically obtuse as such an otherwise cultivated man could be.” Princeton University holds his papers, which include writings, notebooks, correspondence, files from Time, subject files, legal and financial correspondence, photographs, and printed material from 1910 to 1991. These include datebooks 1950-1991. Correspondents include John Aldridge, Whittaker Chambers, T. S. Eliot, Valerie Eliot, Robert Graves, Eleanor Green, Laura Jackson, Schuyler Jackson, Len Lye, Laurie Lee, William Piel Jr., V. S. Pritchett, Lyman Spitzer, and Adlai Stevenson.
