Stephen Davison Bechtel (September 24, 1900 – March 14, 1989) was the son of Clara Alice West and Warren A. Bechtel, the founder of the Bechtel Corporation. He was the president of the company from 1933 through 1960.
Stephen graduated from Oakland Technical High School in 1918, and served with the 20th Engineers, part of the American Expeditionary Force sent to assist France in World War I. After the war, in 1919, he attended the University of California, Berkeley for one year, leaving to work for his father's company full-time. He became vice-president of Bechtel in 1925, and became president in 1933, when Warren Bechtel died suddenly while traveling abroad. His father's death came at a critical time for the company: concrete was being poured for the Hoover Dam, Bechtel's largest project. Stephen became president and saw the company through the construction of the Hoover Dam. Over the next thirty years, he expanded Bechtel into a huge and successful engineering company with operations all over the world. Stephen handed the presidency of the company over to his son, Stephen Jr. in 1960, but stayed on as the chairman until 1969.
He was awarded an honorary degree in Agricultural Science by UC Berkeley in 1954. In 1980, the school completed construction of the Bechtel Engineering Center, which was named in his honor.
Stephen was named by Time magazine as one of the 100 most influential people of the 20th century.
The undergraduate engineering center of the University of California, Berkeley is named the "Bechtel Engineering Center".
The Faculty of Engineering and Architecture at The American University of Beirut (AUB) is named "The Bechtel Engineering Building" after its donor, Stephen D. Bechtel.
