The new American practical navigator: Being an epitome of navigation; containing all the tables necessary to be used with the Nautical almanac in ... and moon, and occultations of the fixed stars
Nathaniel Bowditch was an early American mathematician remembered for his work on ocean navigation. He is often credited as the founder of modern maritime navigation; his book The New American Practical Navigator, first published in 1802, is still carried on board every commissioned U.S. Naval vessel. In 2001, an elementary and middle school in Salem was named in his honor.
