Introduction

Othmar Hermann Ammann (1879–1965) was born in Switzerland, came to the United States in 1904, and was naturalized in 1924. He served from 1925–1939 with the Port of New York Authority and was its director of engineers from 1937 to 1939. An authority on bridges, he participated in either the designing or the construction of Hell Gate, George Washington, Triborough, Bronx-Whitestone, and Verrazano-Narrows (at its opening in 1964, the longest and heaviest suspension bridge in the world) bridges in New York City, and San Francisco’s Golden Gate Bridge.
