What are some interesting facts about Herbert Hoover?

One interesting fact about Herbert Hoover is that he was raised as a Quaker. His parents, who died when he was young, were Quakers, and after their deaths he was raised by Quaker relatives and attended Friends Pacific Academy in Newberg, Oregon. This is of interest because the Quakers, though once a very large group of settlers in America, had dwindled to a tiny sect by the twentieth century, yet they produced two United States presidents in forty years. (Neither one was very successful.)
Another interesting fact is that Hoover actually was a self-made man. Unlike many presidents, including his rival, Franklin Delano Roosevelt, he was not born with a fortune to back him up. He worked his way up on his own, starting his working life as a manual laborer in gold mines. He then became a mining engineer, began his own company, and became very wealthy. Interestingly, too, and much rarer at the time, Hoover was able to travel the world and see other countries up close and personal through his work.
Hoover was criticized at the start of the Great Depression for his lack of compassion. Quakers had a reputation for humanitarian work, and many couldn't understand why this Quaker-raised president didn't do more to help the vast number of people who were in desperate circumstances. History has shown his heart was in the right place, but his background as a self-made man also inclined him to believe people could pull themselves up by their own efforts. He did not sufficiently understand that in a collapsed economy with no capital to be lent and no opportunities available, that can be an almost impossible proposition.
