In 1991, when Steve Jobs was still at NeXT, the company he founded after leaving Apple(s aapl), the FBI opened a file on him. He was up for a presidential appointment, so the bureau was charged with clearing him via a thorough background check.
The document of the things they found is available here.
The FBI talked to many of his acquaintances and “covered inquiries in the United States as to [Jobs’] character, loyalty and general standing.” None of the findings are particularly eye-opening if you’ve read his biography, but it is yet more insight into a fascinating man who at one point put off the investigators for “three weeks” rather than talking to them.
It’s actually kind of amusing to read things in stiff, official bureaucrat-ese like:
“Two individuals, who were acquainted with Mr. Jobs while they were employed at ACI, offered favorable comments concerning Mr. Jobs. They stated that he is strongwilled, stubborn, hardworking and driven, which they believe is why he is so successful. They further stated, however, that Mr. Jobs possesses integrity as long as he gets his way: however, they did not elaborate on this.”
Most of the names of the people interviewed about Jobs are redacted, but if you know his personal history well enough, it’s easy to figure out who they talked to.
