Samuel Eliot Morison participant of World War I
Scholar and historian (1913–1941)
Morison originally intended to major in mathematics until Albert Bushnell Hart talked him into researching some papers of an ancestor stored in his wine cellar. His Harvard dissertation was the basis for his first book The Life and Letters of Harrison Gray Otis, Federalist, 1765–1848 (1913), which sold 700 copies. After earning his Ph.D. at Harvard, Morison became an instructor in history at the University of California, Berkeley in 1912. In 1915 he returned to Harvard and took a position as an instructor. During World War I he served as a private in the US Army. He also served as the American Delegate on the Baltic Commission of the Paris Peace Conference until June 17, 1919.In 1922–1925 Morison taught at Oxford University as the first Harmsworth Professor of American History. In 1925 he returned to Harvard, where he was appointed a full professor. One of several subjects that fascinated Morison was the history of New England. As early as 1921 he published The Maritime History of Massachusetts, 1783–1860. In the 1930s Morison published a series of books on the history of Harvard University and New England, including Builders of the Bay Colony: A Gallery of Our Intellectual Ancestors (1930), The Founding of Harvard College (1935), Harvard College in the Seventeenth Century (1936), Three Centuries of Harvard: 1636–1936 (1936), and The Puritan Pronaos (1936). In later years, he returned to the subject of New England history, writing The Ropemakers of Plymouth (1950) and The Story of the 'Old Colony' of New Plymouth (1956) and editing the definitive work, Of Plymouth Plantation, 1620–1647 (1952).During his time at Harvard, Morison became the last professor to arrive on campus on horseback.  He was chosen to speak at the 300th Anniversary celebration of Harvard in 1936 and a recording of his speech is included as part of the "Harvard Voices" collection.In 1938 Morison was elected as an honorary member of the Massachusetts Society of the Cincinnati.
In 1940, Morison published Portuguese Voyages to America in the Fifteenth Century, a book that presaged his succeeding publications on the explorer, Christopher Columbus. In 1941, Morison was named Jonathan Trumbull Professor of American History at Harvard. For Admiral of the Ocean Sea (1942), Morison combined his personal interest in sailing with his scholarship by actually sailing to the various places that Columbus explored. The Harvard Columbus Expedition, led by Morison and including his wife and Captain John W. McElroy, Herbert F. Hossmer, Jr., Richard S. Colley, Dr. Clifton W. Anderson, Kenneth R. Spear and Richard Spear, left on 28 August 1939 aboard the 147 foot ketch Capitana for the Azores and Lisbon, Portugal from which they sailed on the 45 foot ketch Mary Otis to retrace Columbus' route using manuscripts and records of his voyages reaching Trinidad by way of Cadiz, Madeira, and the Canary Islands. After following the coast of South and Central America the expedition returned to Trinidad on 15 December 1939. The expedition returned to New York on 2 February 1940 aboard the United Fruit liner Veragua. The book was awarded the Pulitzer Prize in 1943.
