Nathaniel Sackett was born on April 10, 1737, in Orange County, New York, into a family of English colonial ancestry. His parents belonged to the stream of settlers moving through the Hudson Valley and adjacent counties during the first half of the eighteenth century. The surviving biographical record is far more informative about his Revolutionary activities than about his childhood, and the names, occupations, and daily circumstances of his immediate household are not consistently reported in standard accounts. It is therefore important to distinguish what is documented from what can only be inferred from his later career. Sackett acquired the literacy, numeracy, and commercial judgment necessary to work as a merchant. In colonial New York, such skills might be learned through family business or apprenticeship rather than college. Merchants needed to maintain accounts, evaluate credit, correspond over long distances, arrange transportation, and judge the reliability of many different people. These habits later proved directly relevant to intelligence work, which depended upon discreet networks, careful reporting, and the ability to conceal unusual expenses within ordinary commercial activity. As a young man Sackett settled in Dutchess County and became involved in land and business affairs. He established a home in the Fishkill area, a strategically important Hudson Valley community linked to river traffic and inland roads. He married and raised a family, becoming sufficiently established to take part in local public life. His neighbors came from varied ethnic, religious, and political backgrounds, circumstances that required a successful businessman to understand loyalties and personal relationships throughout the region. By the imperial crisis of the 1760s and 1770s, Sackett had accumulated both local knowledge and a reputation for commitment to the Patriot cause. He participated in revolutionary committees and political organization before receiving any secret assignment. Thus his later selection by George Washington to develop an intelligence network did not arise from a mysterious or adventurous youth. It rested on quieter foundations: a Hudson Valley upbringing, practical mercantile training, property and family responsibilities, community trust, and years spent learning how information, money, and influence moved among ordinary people.
