Visiting Brooklyn Historical Society (BHS) was a wonderful opportunity for me to know more about Brooklyn. BHS has rich collections from Brooklyn’s history including various maps and photographs. Looking at those maps and photographs, I could picture Brooklyn of century ago. The Atlas of New Utrecht, 1874 gave me some idea about the urbanization of Brooklyn. I could see some estates under the name of person and some estates under the name of development companies. As I understood, these development companies bought the farmer’s land and made it commercial by plotting the land and constructing buildings and apartments houses. After the map, I looked at a photograph of Coney Island Beach, which was taken in July 1958. Comparing today’s Coney Island with the photograph, I found a huge difference. I could see crowd of people enjoying at the beach, but there were no boardwalk and houses were just under construction. This means the Coney Island area was being prepared for commercialization.
