In July 1833, Edmund Blunt (1799-1866) accepted a position as Assistant on the Coast Survey of the National Oceanic and Atmospheric Administration. He remained affiliated with the Coast Survey until his death in 1866. As part of this survey, he and his team mapped the Hudson River shoreline including the area around Newburgh, NY.
Edmund Blunt's father, Edmund March Blunt, a bookseller and publisher, published the first edition of "The American Coast Pilot," one of the most popular pilot guides used by both American and foreign seamen. The Blunt family produced 21 editions of this important work. The Blunt's bookstore, the "Sign of the Quadrant" in New York City, also sold every edition of the Coast Survey charts. According to the NOAA, the Coast Survey and the Blunt family forged a strong alliance which was beneficial to the maritime interests of the country for over 70 years.
