Reinforced Concrete

In 1867, reinforced concrete was patented by F. Joseph Monier (1823-1906), a gardner in Paris, to reinforce garden tubs, beams and posts. The French inventor had found that the tensile weakness of plain concrete could be overcome if steel rods were embedded in a concrete member. The new composite material was called reinforced concrete, or ferroconcrete. William E. Ward builds (1871-75) the landmark building, first in the U.S. to use reinforced concrete, for a private house in Port Chester, N.Y., It was designed by architect Robert Mook.
