Hoover Dam
Warren Bechtel died unexpectedly in 1933 while in Moscow on business. He was succeeded by his son, Stephen Bechtel Sr., who became both the head of Bechtel and chief executive of the Hoover Dam project. Under his leadership, the Hoover Dam was finished in 1935. The project was the largest of its kind in U.S. history at the time and Bechtel's first megaproject.
