Ralph Modjeski (born Rudolf Modrzejewski; January 27, 1861 – June 26, 1940) was a Polish-American civil engineer who achieved prominence as "America's greatest bridge builder."
He pioneered the use of suspension bridges and oversaw the design and construction of nearly forty bridges that spanned the great rivers of North America, as well as the development of new rail lines. In addition, he trained succeeding generations of American bridge designers and builders, including Joseph B. Strauss, chief engineer of San Francisco's Golden Gate Bridge (which was completed six months after Modjeski's San Francisco–Oakland Bay Bridge).
