Greetings to all forum members, I am from Russia and forgive my English.
I have been collecting stamps with bridges and information about them.
Here is one of my notes:
Robling Johann (1806-1869), born in Muhlhausen (in America took the name John)
a brilliant engineer, businessman, industrialist. He received an excellent education, drew, played the flute, and studied at Erfurt, and then graduated from the Polytechnic University of Berlin,
where he studied philosophy in Hegel.
He worked several years for the government of Prussia, and in 1831 immigrated to the United States. There he got the idea to create a braided steel cable from a thin wire, which he managed to bring to life, and even opened his own factory to produce cables of different purposes.
By the mid-19th century, along with his eldest son Robling managed to build four large bridge suspension system: one in Niagara Falls, two in Pittsburgh and one in Cincinnati. A close look at the bridge in Cincinnati really like Brooklyn, pay attention to the cables that make these hanging bridges and cable-stayed at the same time.
Brooklyn has become the largest, but not the new project in the works of John Robling.
However, it was for him Robling family paid the highest price, first in construction lost a leg and died soon after he Robling.
After some time, earning the bends in the construction of piers, was paralyzed by his eldest son, Washington. And an example of courage may be called the behavior of his wife, Emily Warren Robling, which managed under the direction of his ailing husband to study advanced mathematics, strength of materials, possessed by many other building sciences and completed the main business of family life - the bridge became a symbol of New York.
