John L. Moore, a veteran newspaperman, said he employed a journalist's eye for detail and ear for quotes in order to write about long-dead people in a lively way. He said his books are based on 18th and 19th-century letters, journals, memoirs, and transcripts of official proceedings such as interrogations, depositions, and treaties. The author is also a professional storyteller who specializes in dramatic episodes from Pennsylvania's colonial history. Dressed in 18th-century clothing, he does storytelling in the persona of "Susquehanna Jack," a frontier ruffian. Moore is available weekdays, weekends and evenings for audiences and organizations of all types and sizes. Moore has participated in several archaeological excavations of Native American sites. These include the Village of Nain, Bethlehem; the City Island project in Harrisburg, conducted by the Pennsylvania Historical and Museum Commission during the 1990s; and a Bloomsburg University dig in 1999 at a Native American site near Nescopeck. He also took part in a 1963 excavation conducted by the New Jersey State Museum along the Delaware River north of Worthington State Forest. Moore's 45-year career in journalism included stints as a reporter for The Wall Street Journal; as a Harrisburg-based legislative correspondent for Ottaway News Service; as managing editor of The Sentinel at Lewistown; as editorial page editor and managing editor at The Daily Item in Sunbury; and as editor of the Eastern Pennsylvania Business Journal in Bethlehem.
