MCMASTER, JOHN BACH

born June 29, 1852, Brooklyn, N.Y., U.S. died May 24, 1932, Darien, Conn. American historian whose eight-volume work on the people of the United States was innovative in the writing of social history. The son of a former Mississippi plantation owner, McMaster grew up in New York City and worked his way through the City College of New York. Although he obtained a degree in civil engineering in 1873, he was deeply interested in American history. He worked briefly as a civil engineer in Virginia and Chicago in 1873, but he returned to New York the following year and earned a meagre living by tutoring. McMaster was appointed assistant professor of civil engineering at Princeton University in 1877. Meanwhile, he planned to write a broad-scale history of the United States. In the summer of 1878 he led an expedition to the American West, an experience that impressed on him the pioneers' efforts and the need for a social history of the West. His inspiration materialized in 1881 with the completion of the first chapter of A History of the People of the United States from the Revolution to the Civil War, 8 vol. (18831913). Almost immediately after publication of this first extremely popular volume in 1883, he accepted an offer to teach at the Wharton School of Finance and Economy at the University of Pennsylvania, Philadelphia, where he remained until his retirement in 1919. In 1885 he wrote the second volume of his History, and two years later he completed another work, Benjamin Franklin as a Man of Letters. In addition to writing and teaching, McMaster actively participated in the establishment in 1891 of a new School of American History at the University of Pennsylvania, the first school of its kind in the United States. His widely praised work A School History of the United States, published in 1897, became that same year one of the most widely used textbooks of that time. After completing his History in 1913, he traveled to Europe and returned to the United States to espouse American entry into World War I. He wrote an additional volume of his History (1927), dealing with the administration of President Abraham Lincoln. Although McMaster has been criticized for his excessive glorification of the progress of the American people, his tendency toward exaggeration and sweeping generalization, and his casual uncited borrowing from other sources, he is credited with having placed a novel emphasis on social and economic forces in historical change and on the use of contemporary documents and newspapers as legitimate sources for historical research. He was also one of the first American scholars to stress the role of the American West in national development.
