From the roaring twenties on commonlit - Herbert Hoover was elected the country’s 31st president in 1929. He was a successful mining engineer from Iowa before lending his services to the government. As President Coolidge’s secretary of commerce, Hoover recognized already in 1925 that the economy was overheating as Americans began “buying on margin”22 and speculating23 on the soaring stock market.
