BROOKLYN BRIDGE
Eighth Wonder of The World
May 24, 1883, Brooklyn
Bridge opens after 14 years under construction and 27 deaths,
connecting the cities of New
York and Brooklyn for the first time in history. Thousands of
Brooklyn and Manhattan Island residents turned out to witness the
dedication ceremony presided over by the United States President
Chester A. Arthur and New York State Governor Grover Cleveland.
The bridge was the design
of the late John a. Roebling and is the largest suspension bridge
ever built to date.
Roebling was born in Germany in 1806, studied industrial engineering
in Berlin and when age 25 immigrated to western Pennsylvania where
he became an unsuccessful farmer and later moved to Harrisburg where
he took the job of a civil engineer who promoted the use of wire
cable and soon established a successful wire cable manufacturing
business.
He earned a reputation of
being 'the' designer of suspension bridges which have become widely
in use but were known to fail to high winds and overloading.
Roebling is credited with the technology , a stabilizing truss,
which did indeed stabilize the whole structure. This idea was used
to build bridges at Niagara Falls and Cincinnati.
The state of New York
awarded Roebling the contract to design and construct the 1595 foot
bridge to connect Brooklyn and Manhattan but just prior to the start
of construction, in 1869 , while taking a few final compass readings
across the East River a boat mishap smashed one of his feet and
within three weeks, he died of tetanus and became more than two dozen
people who would die building his bridge.
Roebling's 32 year old
son, Washington A. Roebling, took over as chief engineer since he
had helped his father design the Brooklyn Bridge and assisted with
several bridge construction jobs.
The two granite foundations
of the Brooklyn Bridge were built in timber caissons sunk in 44 feet
of water on the Brooklyn side and on the New york side, in 78 feet
of water, and were pressurized with compressed air, allowing
underwater construction. At that time very little was known about
the risk of working under such conditions. Hundred of workers
suffered Compression sickness or 'bends', and several had died.
Washington Roebling was one himself and in 1872 became bedridden
from the condition.
However, Roebling
continued to direct operations from his bedside at home, his wife,
Emily, would carry his instructions to the workers. During 1877,
Washington and Emily, moved to a home with a view of the bridge.
Washington Roebling
gradually improved but he remained partially paralyzed for life.
On May 24, 1883, Emily
Roebling, carring a symbol of victory, a rooster, in her lap, was
given the first ride over the completed bridge. Within the next 24
hours , more than 250,000 people walked across the Brooklyn Bridge on
the broad promenade above the roadway, designed by John
Roebling, solely for the enjoyment of pedestrians.
