David Barnard Steinman (June 11, 1886

Louis E. Levy Medal in 1957.[5]

David B. Steinman built bridges in the United States, Thailand, England, Portugal, Italy, Brazil, Haiti, Puerto Rico, Canada, Korea, Iraq and Pakistan. He had a literary bent, and was a published author with several books, articles in advancement of his craft, and even had children's books and poetry to his credit.

Early life

Steinman was the child of Jewish immigrants. Little is known of his family and early childhood other than that he had 6 siblings. There is some controversy about where and when he was born. Some sources[6] have him born in Chomsk (Хомск חומסק), Brest, Belarus in 1886, and emigrating to the United States with his family in 1890. However other sources, including Ratigan,[7] and Steinman himself[8] have him born in New York in 1887.

Steinman grew up in New York City, New York, and was raised in the shadows of the Brooklyn Bridge. The Williamsburg Bridge was constructed as he grew up. The late Nineteenth and early Twentieth centuries were a time of significant bridge construction in the area, and he later said this is where he got his first interest in bridges.

Because his family had little money, he worked to put himself through both the

PhD in Civil Engineering. His PhD thesis was on a steel truss arch design for the Henry Hudson Bridge. While he was attending Columbia he did fellowships as well as taught nighttime classes at the City College and Stuyvesant Evening High School. He accepted a teaching position at the University of Idaho in Moscow, Idaho
(1910–1914) but longed to return to New York.

Robinson & Steinman

In May 1920,

Florianópolis Bridge (or Hercilio Luz Bridge, 1926) in Florianópolis, Brazil. After getting advice from Charles Fowler, Steinman agreed and they formed the firm of Robinson & Steinman
in 1921, a partnership that lasted until the 1940s. They did not win the contract immediately but continued to collaborate on it and other projects. The early 1920s were considered a tough time for bridge construction, so Steinman tried to design his bridges to be economically pleasing rather than artistic, without sacrificing the structural integrity of the bridge. For example, Robinson and Steinman changed the original plans for the Florianopolis bridge, using eyebar chains as the upper chord of the stiffening truss instead of the conventional wire-cable. The new design produced a very stiff bridge with much less material than the original plan. Other bridge engineers would also have to take this new economical design into account when competing with Steinman. Steinman was well regarded in the profession and had a reputation for good presentations and for being politically astute.


The 1920s and 1930s were a relatively busy period for Steinman. His firm was involved in many significant projects including the

Sullivan-Hutsonville Bridge
(both 1939).

In addition to the many bridges that Steinman designed, he was consulted on several projects that his firm did not win. Perhaps the most famous of these bridges is "Galloping Gertie," the original Tacoma Narrows Bridge. Steinman consulted extensively with the boosters of the bridge during the 1920s, but his design was not selected. He wrote of his frustration with the design that was chosen, and predicted a failure. He presented his findings at the 1938 meeting of the structural division of the American Society of Civil Engineers. In the audience was the designer of the Tacoma Narrows Bridge, which was under construction at the time. The failure did occur and he wrote that it had a profound impact on his design principles; he became even more conservative. It is said that he designed the Mackinac Bridge to withstand winds of 365 mph. It is considered by many to be his most significant work, although, perhaps not by Steinman himself, who expressed a personal preference for the St. Johns bridge, saying, "If you asked me which of the bridges I love best, I believe I would say the St. Johns bridge. I put more of myself into that bridge than any other bridge."

During this period Steinman became president of the American Association of Engineers and campaigned for more stringent educational and ethical standards within the profession. He also founded the National Society of Professional Engineers in 1934, serving as its first president. By the mid-1930s Steinman had a professional reputation as one of the pre-eminent bridge engineers of the US, especially for long span suspension bridges, but his bridges were eclipsed in the public eye by his old rival Ammann's George Washington Bridge (1931) and by Joseph Strauss's Golden Gate Bridge (1937) among others. His plans for a NYC cross harbor bridge (the "Liberty Bridge") came to naught with the 1940 collapse of Tacoma Narrows which cast all long suspension span proposals in doubt.

Postwar work

Steinman and his firm were also in charge of the major rehabilitation of the Brooklyn Bridge commencing 1948. Structurae.de has an image of Steinman jauntily perched in mid air in the cables of the bridge, perhaps one of the best known images of him.

Steinman's crowning achievement, the "Mighty Mac" or Mackinac Bridge

But there were still long span suspension bridges to be built. Steinman was responsible for the

Michigan State Legislature
legislation of 1950, stating "the board of engineers retained by the Mackinac Bridge Authority was to be selected and nominated by the Dean of Engineering at the University of Michigan," and was soon the spokesman for the board. But his health was failing and he suffered heart attacks in 1952, the same year the legislature approved funding. He was nevertheless heavily involved in all aspects of the construction of the bridge from start to finish.

From the beginnings of his work on the Mackinac Bridge, Stewart Woodfill was impressed with Steinman's ethical procedure in addressing his requests. In 1950 new legislation was produced stating "the board of engineers retained by the Mackinac Bridge Authority was to be selected and nominated by the Dean of Engineering at the University of Michigan" (Ratigan 280). This was to make sure that there was no political influence in this decision. Steinman was selected to be a member of the board. Steinman who had been trained since he was young to work well in groups was chosen as the spokesman for the board. When it comes to speaking in front of large audiences Steinman does it naturally. It was said that Steinman spoke "as comfortable before large audiences as he was on tall bridges" (Petroski 332). The stresses of the early stages of the bridge soon took their toll on Steinman. He had heart attacks in 1952, which was the same year that legislation approved the financing and construction of the bridge.

Although he proposed the project of the

Straits of Messina, the "Mighty Mac," completed in 1957, and at the time the longest suspended span between anchors, was his last major achievement. In 1960, he was elevated as the 16th National Honor Member of Chi Epsilon
national civil engineering honor society. Steinman died in 1960.

At the time of his death, he was president of the Society for the History of Technology.

--Tribute—In closing, Dr. Dunn said this about the need for a broader education for engineers, "If the engineer's training neglects the great human mirrors of history and languages, if his heart and mind are insensible to the great social forces, if he but feebly develops the subtle qualities of character that make for personality, his career is limited, no matter how much science he knows" (Ratigan 315).

The Steinman engineering firm is now part of the Parsons Corporation as of 1988.

Personal life and hobbies

At the age of 63, Steinman took interest in poetry. Many people wrote to him saying his bridges represented poems. This inspired him to start writing. His love for bridge building was reflected in his writing, which can be seen in the titles of two of his poems, "The Bridge" and "I Built a Bridge". He received much recognition for his poetry; many poems were published in various newspapers and magazines as well as in the book "I Built a Bridge and Other Poems," published in 1955. Steinman became involved in leadership roles in many poetry groups including the president of the Wisconsin Poetry Foundation and director of the Poetry Institute in New York.

"A bridge is a poem stretched across a river, a symphony of stone and steel"

a line from his poem[10] Brooklyn Bridge - Nightfall[11]
