Othmar H. Ammann (1879 to 1965)

Othmar Ammann began a renowned career in bridge engineering after immigrating to New York City from Switzerland in 1904. Working with Gustav Lindenthal in 1912, Ammann was the Assistant Chief Engineer for the Hell Gate and Sciotoville Bridges. A conceptual design for the George Washington Bridge in 1921 earned Ammann employment with the New York Port Authority.

Under his direction, this famous Hudson River crossing was completed in 1931, six months ahead of schedule and under budget. Ammann served as the Port Authority’s Director of Engineering until 1939 where he oversaw construction of the Goethals and Outerbridge Crossing Bridges and the Lincoln Tunnel. While serving at the Port Authority in 1934, Robert Moses retained Ammann to also serve as Chief Engineer for the Triborough Bridge and Tunnel Authority (TBTA) where he engineered the Triborough and Bronx-Whitestone Bridges.

With his impressive reputation in bridge engineering, Ammann was invited to serve on the board of engineers for the Golden Gate Bridge in California and held consulting roles on many other bridges. In 1939, Ammann resigned from the Port Authority and TBTA to pursue a career as a private consulting engineer.
