Painters on the cables of the Brooklyn Bridge, October 7, 1914
De Salignac, had worked for the Department of Bridges (later the Department of Plant and Structures) from 1903 to 1934. Vast reaches of infrastructure were laid down in those years, and his job was to provide a record: he shot the construction of the Manhattan and Queensboro Bridges and the Municipal Building; subway tunnels, trolley lines, and ferries.
