The Norvin H. Green collection consists of ca. 60 albums, some disassembled, containing ca. 4,000 photographic prints, 5 x 7 in.; ca. 300 loose prints (most 5 x 7 in.); and ca. 3,750 film negatives, most are 3 1/2 x 2 1/2 in., ca. 650 are 5 x 7 in. (The online collection currently consists of the negative materials only.) Green compiled a photographic record of New York elevated railroads that focuses on the dismantling of most of the lines between 1939 and1941, hiring the firm of H.F. Dutcher to document the demolition in almost 4,000 views. Views show the changes block by block as the heavy skeletal structure and stations were removed along Manhattan's Sixth Avenue line (1939), Ninth Avenue line (1940), and Second Avenue line (1941); and along Brooklyn's Fifth Avenue, Fulton Street, and Sands Street lines (1941). Brief captions identify each street address and date. Comments on girder weight, crane operation, and special demolition feats accompany the Brooklyn line views. ; Norvin Hewitt Green (1894-1955) was a business executive, civic leader, railroad enthusiast, and trustee of The New-York Historical Society.
