Input: Question: Which of the authors employed by Scribner's Magazine to write about the First World War was the olderst? Passage:Scribner's Magazine was the second periodical publication of the Scribner's firm, after Scribner's Monthly was published from 1870 to 1881. Scribner's Monthly was later moved to another publisher, and renamed The Century Illustrated Monthly Magazine. Charles Scribner announced to a New York Times reporter that they would make a new monthly publication "as soon as the necessary arrangements could be perfected". It was also announced that the editor would be Edward Burlingame, the son of Anson Burlingame, who was already connected to the publishing house as literary adviser. Charles Scribner also noted that the magazine would not be a revival of the formerly published Scribner's Monthly. Charles Scribner's Sons spent over $500,000 in launching Scribner's Magazine to complete with the already successful pictorials, The Atlantic Monthly and Harper's Magazine. Burlingame hired the best artists in his country for the magazine; Howard Pyle, Howard Chandler Christy, Charles Marion Russell, Walter Everett, Maxfield Parrish and Frederic Remington. Before the first issue was released, Charles Scribner's Sons had their first annual "Scribner's Magazine" dinner at their main offices. Scribner's Magazine was launched in January 1887, the first issue of which was to be published from January to June of that year. The magazine was printed and bound by Trow's Printing and Bookbinding Company. Scribner's Magazine was also the first magazine to introduce color illustrations later on. The first issue opens with the literary article "The Downfall to the Empire." by E.B. Washburne, the former minister to France. An early morning fire in 1908 at the Charles Scribner's Sons offices heavily burned the third and fourth floors, where the magazine was produced. In May 1914, the magazine's editor, Edward L. Burlingame, retired and Robert Bridges took over as editor. (Bridges was a lifelong close friend of President Woodrow Wilson ever since the two had met as students at Princeton University.) During the First World War, the magazine employed authors, Richard Harding Davis, Edith Wharton and John Galsworthy, to write about the major conflict. During the time of 1917, when the United States joined the war, the magazine had four to six articles on the subject. On the date of November 19, 1922, the first editor of the magazine, Edward L. Burlingame, died. On January 1928 the magazine had a change in format, with the first of the newly formatted issue having a cover design by Rockwell Kent.
