Herbert Hoover, 1929-1933 – $82 Million

In 1929, the Great Depression set in on America, and Herbert Hoover took office at the same time. He was a mining engineer before he became president. He signed the law to make the Star Spangled Banner the National Anthem of America. Most of his wealth came from his work as a mining engineer and the very successful investments he made in mines around the world, reaching a net worth of $82 million. He gave his Presidential salary to charity because he REALLY didn’t need it. After retiring from office, he began to write books.

The next President came to power after a traumatic event, but he was as tough as they come. Guess who!
