Imagine being able to stand on Main Street in Cold Spring more than a century ago and know exactly what stood on nearly every corner. What was made of wood, what was built of brick, where the blacksmith worked, where businesses operated, and even where the nearest fire hydrant could be found. The closest thing we have to such a time machine may be the Sanborn Fire Insurance Map.
Way Back Wednesday:
Where was that building originally built? What type of business was located there? What was the structure made of, and what were its dimensions? These are just a few of the questions that come to mind when Cold Spring historians examine buildings or houses seen in historic photographs. Thankfully, Sanborn Fire Insurance Maps can provide some important information to assist us with our photographic detective work. The maps were named after the creator Daniel Alfred Sanborn. In 1867 Sanborn founded the D.A. Sanborn National Insurance Diagram Bureau which was headquartered in New York City; this small company was destined to become the premier fire-insurance mapping company in America. The Sanborn map wasn’t originally designed as a tool for historical use, but rather as an aid to agents underwriting fire insurance policies. Because insurance companies needed accurate information, surveyors recorded a town’s layout and buildings in painstaking detail; this is what makes these maps a welcome historical aid today. The Library of Congress is the largest holder of these Sanborn maps with some 780,000 sheets on file including this Cold Spring sectional (bold black lines indicate multiple map sections) 1895 map.
