William Gienapp

William E. Gienapp (February 27, 1944 – October 29, 2003) was an American historian noted for his writing on the period of the American Civil War. His prize-winning The Origins of the Republican Party, 1852-1856 was based on original research and revised the traditional understanding of the political party's origins. Later he wrote Abraham Lincoln and Civil War America: A Biography (2002). He co-authored a widely used United States history textbook, Nation of Nations, and compiled one of the most widely used documentary readers on the era of the Civil War, The Civil War and Reconstruction: A Documentary Collection (2001).

Education and career Gienapp held a B.A. and Ph.D. from the University of California, Berkeley, where he studied under Kenneth Stampp, and an M.A. from Yale University. After earning his doctorate in 1980, Gienapp began working at the University of Wyoming. He became a visiting associate professor at Harvard in 1988 before formally joining the faculty the following year. Gienapp died prematurely in the fall of 2003 at the age of 59 from complications surrounding a rare form of blood cancer. He was survived by his wife and two sons.

During his tenure at Harvard University, Gienapp acquired a reputation as a teacher and mentor of graduate students. In addition to teaching popular courses on the American Civil War, Reconstruction, and antebellum America, he also taught a popular course on the history of baseball in the United States.
