One colorful anecdote from that period.

> In the United Kingdom, he was called "Slater the Traitor" and "Sam the Slate" because he brought British textile technology to the United States, modifying it for American use. He memorized the textile factory machinery designs as an apprentice to a pioneer in the British industry before migrating to the U.S. at the age of 21.
