Most presidents come from an academic or professional background that involves letters -- law, writing, maybe journalism or education. Few bring to the office what one might call a technical background.
Only one, Herbert Hoover, was in the strictest sense an engineer by trade. And only one other president, Jimmy Carter, studied engineering in college. However, several of our earliest presidents worked as land surveyors, a lost art that involves a technical mastery of cartography. Some have labored with their hands and minds in similar conditions as electrical engineers today. Others have faced technological transformations while in office.
For this Presidents' Day, we look back at seven Presidents who thought the way engineers do -- seven of the most technical leaders of the free world.
The White House has had a few engineering-minded occupants.
