Arthur Walworth, 101, author of a Pulitzer Prize-winning biography of Woodrow Wilson, died of cardiac arrest Jan. 10 in Needham, Mass.
Mr. Walworth began studying Wilson's life after World War II at the advice of Harvard University professor Arthur Schlesinger Sr. The biography took 10 years to write, as Mr. Walworth interviewed numerous Wilson associates and traveled to the United Kingdom and France to examine documentary sources.
His two-part biography, "Woodrow Wilson, Volume I: American Prophet" and "Woodrow Wilson, Volume II: World Prophet," was first published in 1958. The following year, he was awarded the Pulitzer for the first volume.
Mr. Walworth wrote on the history of U.S. diplomacy after World War I when a mentor from Yale University, Charles Seymour, couldn't finish the project because of poor health. That history also was published in two volumes: "America's Moment: 1918" (1977) and "Wilson and His Peacemakers: American Diplomacy at the Paris Peace Conference, 1919" (1986).
Mr. Walworth was born in Newton, Mass., where he lived most of his life. He graduated from Phillips Andover Academy in 1921 and from Yale in 1925. He taught English in China for a year, then worked in the educational department at Houghton Mifflin Co.
He left during World War II for a brief stint as a broadcast writer for the Office of War information before undertaking the Wilson biography.
Survivors include a sister, Elizabeth Walworth Ross of Essex, Conn.
