Alexander Dallas Bache (1806-1867) was an incredibly prolific surveyor, who worked as the superintendent of the United States Coast Survey, which was first established in 1807. Over the course of the 19th century, the survey worked closely with the U.S. Navy to produce sea charts of the country's waters that could serve scientific as well as military functions.
