Othmar Hermann Ammann (March 26, 1879 – September 22, 1965) was a Swiss-American structural engineer whose designs include the George Washington Bridge, Verrazano-Narrows Bridge, and Bayonne Bridge. He also directed the planning and construction of New York City's Lincoln Tunnel.

Biography

Othmar Ammann was born nearby Schaffhausen, Switzerland in 1879. His father was a manufacturer and his mother was a hat maker. He received his engineering education at the Polytechnikum in Zürich, Switzerland. He studied with Swiss engineer Wilhelm Ritter. In 1904, he emigrated to the United States, spending his career working mostly in New York City. In 1905 he briefly returned to Switzerland to marry Lilly Selma Wehrli. Together they had 3 children- Werner, George, and Margaret- before she died in 1933. In 1924, he became a naturalized citizen of the United States. He then married Karly Vogt Noetzli in 1935 in California.

Ammann wrote two reports about bridge collapses, the collapse of the Quebec Bridge and the collapse of the original Tacoma Narrows Bridge (Galloping Gertie). It was the report that he wrote about the failure of the Quebec Bridge in 1907 that first earned him recognition in the field of bridge design engineering. Because of this report, he was able to obtain a position working for Gustav Lindenthal on the Hell Gate Bridge. By 1925, he had been appointed bridge engineer to the Port of New York Authority. His design for a bridge over the Hudson River was accepted over one developed by his mentor, Lindenthal. (Lindenthal's "North River Bridge" designs show an enormous, 16+ lane bridge that would have accommodated pedestrians, freight trains, rapid transit, and automobile traffic. The bridge, which would have entered Manhattan at 57th Street, was rejected in favor of Ammann's designs primarily due to cost reasons.)

Ultimately, this became the George Washington Bridge. Under Ammann's direction, it was completed six months ahead of schedule for less than the original $60 million budget. Ammann's designs for the George Washington Bridge, and, later, the Bayonne Bridge, caught the attention of master builder Robert Moses, who drafted Ammann into his service. The last four of Ammann's six New York City bridges — Triborough, Bronx-Whitestone, Throgs Neck, and Verrazano-Narrows — were all built for Moses' Triborough Bridge and Tunnel Authority. In 1946, Ammann and Charles Whitney founded the firm Ammann & Whitney. In 1964, Ammann opened the Verrazano Narrows Bridge in New York, that had the world's longest suspended span of 4,260 feet (1,300 m), and the world's heaviest suspension bridge of its time. The Verrazano Narrows Bridge is currently the eighth-longest span in the world and longest in the Western Hemisphere. Ammann also assisted in the building of the Golden Gate Bridge in San Francisco, currently ranked ninth.

Legacy

Through his career, Ammann was the recipient of several awards, including the Thomas Fitch Rowland Prize (1919), the Metropolitan Section Civil Engineer of the Year (1958), the Ernest E. Howard Award (1960) and the National Medal of Science (1964).

In 1962, a bronze bust of Ammann was unveiled in the lobby of the George Washington Bridge Bus Station.[1][8] A residence hall called Ammann College was dedicated in his honor on February 18, 1968 on the campus of Stony Brook University.[9] To mark the hundredth anniversary of his birth, a memorial plaque for Ammann was placed near the Verrazano Narrows Brid
