The Brooklyn Bridge was designed by John A. Roebling (who could not  attending the end of his work because of tetanus caused by a serious accident due to the crash of a ferry against the quay).  Construction began in 1869 and was completed in 1883. At the time, it was the longest suspension bridge in the world. The Brooklyn Bridge connects the boroughs of Manhattan and Brooklyn by spanning the East River.

The Brooklyn Bridge was designated a National Historic Landmark in 1964 and a National Historic Civil Engineering Landmark in 1972.

Construction of the bridge was then left to his son, Washington Roebling , who worked on the foundation pits. However, after a short time, he suffered from decompression syndrome, a very common illness among divers, and had to take time off from work.

​

Finally the work remained in the hands of his wife, Emily Warren Roebling , who had to learn engineering to become the main assistant. When it was opened to the public, she was the first to walk through it.
