William Bell Clark (September 26, 1889 – October 31, 1968) was an advertising executive and self-taught naval historian, specializing in the period of the American Revolution, 1775-1783.

Early life and education
Born in Mechanicsburg, Pennsylvania, William Bell Clark was the son of William Patterson Bell and Kate Stees Bell.  He graduated from Harrisburg Technical School (Pennsylvania) in 1907 and married Grace Mildred Wrigley on 5 November 1915, with whom he had two sons: William Bell Clark, Jr., and Donald Wrigley Clark.

Professional and writing career
From 1907 to 1919, he worked in the newspaper business in Harrisburg and Philadelphia. He served as Assistant Secretary of the Pennsylvania War History Commission, 1919-1921. In 1921, he moved to Evanston, Illinois and joined the N. W. Ayer & Son Advertising Agency, rising to be vice president in 1939 and later, president.

Although his first book was on military history, his work with the Pennsylvania War Commission from 1919 sparked his initial interest in naval affairs. He wrote several biographies of American naval captains, including John Barry (1745-1803), Nicholas Biddle (naval officer), Lambert Wickes, and John Young (naval officer) during the American Revolution, which were published by prominent academic presses, such as the Yale University Press and Louisiana State University Press. In the process of this research and writing, Clark developed a deep knowledge of the archival resources for this general period in naval history and made numerous careful transcripts of documents. As a result of this in the late 1950s, Clark's work came to the attention of the Director of Naval History, Rear Admiral Ernest M. Eller at the Naval History Division of the Navy Department (now the Naval Historical Center) and the head of the Early History Branch in that office, Dr. William J. Morgan. With the advice of the Secretary of the Navy's advisory sub-committee on naval history, Clark was appointed the first editor of the U.S. Navy's multi-volume documentary series on Naval Documents of the American Revolution, assisted by Morgan and his staff in the Early History Branch.  Clark died while the fourth volume was in the course of publication, but left rough drafts for the first ten volumes. He was succeeded as editor and his work continued by Dr. William J. Morgan, who in turn was succeeded by Dr. William S. Dudley, and then by Dr. Michael J. Crawford.

A Republican and a Presbyterian, Clark was also a member of the Naval Historical Foundation, the Historical Society of Pennsylvania, the Pennsylvania Genealogical Society, and served as vice president of the Illinois chapter of the Sons of the American Revolution. Clark's personal small 170 document collection of original manuscript material, the bulk relating to the 1770-1794 period, with some documents as late as 1950, is in the Manuscript Division at the Library of Congress.
