Hoover was a pretty amazing man and a pretty miserable president. A mining engineer who made his pile working in China. He claimed he was literally first Stanford University student (he showed up days early when the college first opened and he stayed in the dorms by himself.)

He and his wife (who was also a geologist) were fluent in Chinese and would speak in it if they wanted privacy.

He became known for international humanitarian missions during and after the first world war. He became a national figure by directing flood relief operations during the 1927 Mississippi Flood, which catapulted him into the White House a year later.

He was a much better humanitarian than he was a president. And pretty good geologist and linguist too.

He was also chosen to tour and report on post-Second World War Germany due to his experience from similar humanitarian missions he undertook in Europe in the aftermath of the First World War.

Does anyone think that it's possible that there will be another career engineer as POTUS? I've heard that there remains a sort of stigma to such a thing, perhaps in part due to the Hoover administration.

I don't know why there would be a stigma on engineers and not not college professors. Wilson was a far worse president than Hoover.

Eisenhower was the President of Columbia University. Clinton and Obama both taught in Law Schools.

I think there's a better batting average for college professors than engineers.
