Nathan was born in Groton, Connecticut, on April 24, 1750. As a child, the young Nathan received little formal education, studying for short time at the local school and then with an area tutor. Despite his lack of formal education, Nathan was born with a natural aptitude for mathematics. As a very young man, Nathan earned his living as a barrel-maker.

Because of his remarkable ability with math, an early colonial publisher of almanacs asked Nathan to calculate almanac entries for his books. Daboll accepted this position, and in 1771 began submitting almanac entries under the alias Edmund Freebetter. Before long, the gifted educator began to publish almanacs and registers under his own name. Almanacs were sometimes used as instruments of propaganda during the years of the American Revolution. Some of Daboll’s almanacs contained satirical or factual political commentary.

Thriving in an academic atmosphere, Nathan accepted a position as a teacher of mathematics at the Academic School in Plainfield, Connecticut. He taught there from 1783 to 1788. This remarkable educator is probably best known for writing a comprehensive math textbook, The Complete Schoolmaster’s Assistant: Being a Plain, Practical System of Arithmetic, which was published in 1799 and used extensively in American schools for nearly fifty years thereafter.

Nathan, who taught navigation to members of the merchant marine and the navy during the Revolutionary War, was also quite notable for the post-war maritime navigation school he founded in New London, Connecticut. There he taught navigation and nautical astronomy to as many as 1,500 sailors. In 1811, Nathan became an instructor of midshipmen on the frigate President.

This amazing chalkboard champion passed away in Groton, Connecticut, in 1818, at the age of 67.
