Nathan Daboll ( – March 9, 1818) was an American teacher who wrote the mathematics textbook most commonly used in American schools in the first half of the 19th century.〔Bunt 1988:33〕 During the course of his career, he also operated a popular navigation school for merchant mariners, and published a variety of almanacs during the American Revolution period. ==Early years== Born in Groton, Connecticut, Daboll was the son of Nathan Daboll (born c. 1725 in East Hampton, New York; died c. 1780) and Anna Lynn (born 1724 in Groton). He had two brothers, John (born 1755) and Benjamin (1757–1848), and two sisters Susannah (born 1748) and Amy (born 1764). Daboll's father was born with the surname Dibble, but changed it to Daboll. Daboll's grandfather was born with the surname Dibble (sometimes spelled Deble). Daboll had little formal education but mastered mathematics quickly while earning a living as a cooper.〔Stowell 1976:92〕
