who was president when the hoover dam was built
Hoover Dam Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam by a joint resolution of Congress in 1947. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. The dam was named after President Herbert Hoover.
Construction of Mount Rushmore Having decided on the location of the sculpture, Borglum decided to make the monument of four presidents of the United States. He chose the two most famous presidents in American history, George Washington and Abraham Lincoln. He chose Thomas Jefferson because Jefferson nearly doubled the size of the United States in the 1803 Louisiana Purchase (which included the land that became South Dakota). The last president Borglum chose was Theodore Roosevelt, suggested by President Calvin Coolidge (who insisted that at least there be two Republicans and at least one Democrat represented)[2] because of Theodore Roosevelt's introduction of the National Park Service.
