About the author
Born in Hartford, Connecticut, in 1871, Clive Hart Day was an American economic historian, teacher, and author. He graduated from Yale in 1892, pursued further study in Berlin and Paris, and went on to teach at the University of California before joining Yale, where he became a professor of economic history.
Day is especially remembered as the author of A History of Commerce, a widely noted work in its field. Beyond the classroom, he served as chief of the Balkan Division for the American Commission to Negotiate Peace in Paris in 1918–1919, showing how closely his academic interests connected with international affairs.
His papers at Yale also reflect later public work, including service connected to employment policy in Connecticut. He died in 1951, leaving behind a career that combined careful scholarship, teaching, and practical engagement with the economic issues of his time.
