Industrialist Henry J. Kaiser begins construction of the Boulder Dam (later Hoover Dam), embarking on one of America’s greatest engineering projects.
On July 7, 1930, Henry J. Kaiser launched construction of the Boulder Dam on the Colorado River. Renowned for his shipbuilding ventures, Kaiser partnered with the U.S. government to create a massive concrete structure. The dam aimed to provide hydroelectric power, water storage, and flood control to the American Southwest. Thousands of workers faced harsh desert conditions and risky work for months-long shifts. The project symbolized American ingenuity and industrial might during the Great Depression. Completed in 1936 as Hoover Dam, it remains a testament to large-scale infrastructure achievement.
