Old South Brooklyn Entrepreneur is far more than a financial and commercial biography of Anson Blake 1789-1868. It provides many details of local history, not only of South Brooklyn (today's Cobble Hill, Carroll Gardens, Red Hook, Boerum Hill and Gowanus) before the Civil War, but of New York City's economic history, including Anson Blake's speculation in Wall Street area lands and buildings. Blake also speculated in Upstate New York's Black River Canal region of Oneida, Hamilton and Herkimer counties where Anson Blake wanted a railroad to be built through his lots. Many interesting illustrations and photographs depict facets of Manhattan and Brooklyn history — including Blake's early land and building speculation enterprises in South Brooklyn adjacent to the terminus of the original Long Island Railroad, and the Atlantic Street and Hamilton Avenue ferries. This book describes New York's and Brooklyn's history during the second quarter of America's 19th century.
