STERN AND HUMORLESS, JOHN ROEBLING LOVED NOTHING SO MUCH AS ENGINEERING

PARALYZED BUILDER sits in view of bridge, beside binoculars through which he watched it grow.

MODERN RENOVATOR who drew the plans for the recent changes is David Steinman, here standing on its strands. He is one of the world's great bridgebuilders, with 300 spans on five continents.

These are the bridgebuilders, a dedicated lot. Such a one was John A. Roebling. A German-born civil engineer who immigrated to America in 1831, Roebling helped found a colony in Pennsylvania, saw the need for an iron rope and began to make it. He not only invented iron (later steel) cable, but he epochally incorporated it into the suspension bridge by developing a technique for weaving wire back and forth from shore to shore without a break, first in strands and ultimately into cables. Bridgebuilding became his life work and 1,595-foot Brooklyn Bridge his epitaph. For one day in 1869, while he was surveying its site, a ferry crushed his foot and 16 days later he died at 63. But foresighted Roebling had planned properly, even to a successor who went on - as the pictures on the following pages relate - to finish the engineering masterpiece.
WORK WAS DIRECTED BY REMOTE WATCHER
The month after John Roebling died, his son, Washington Roebling, 32, Civil War veteran and graduate-engineer, assumed his father's duties. Work on the bridge began in January 1870. It proceeded well although as the caissons ate into the river's bed, workmen died of the then mysterious "bends," or caisson disease. Stanch Roebling spent more time in the caissons than anyone. In 1872 he too was stricken, rallied and returned to be stricken again - terribly. He was paralyzed, his sight, hearing and speech affected, his nervous system reduced to a life-long torment. From his home in Brooklyn (above) he continued directing the work and his magnificent wife Emily studied engineering so she could make inspections - and transmit his orders to job engineers.
