William Perris was a first in producing fire insurance maps for Brooklyn. The Great fires in 1835 and 1845 that destroyed large sections of the New York City made it clear to insurers the utility of knowing what buildings were made of and what hazards might be in them.
Here is the key to the color of the buildings: pink means brick, yellow means wood a wooden structure.
Below are select plates from Perris's 1861 map showing sections of the Red Hook waterfront:
