> https://en.wikipedia.org/wiki/Peter_Thiel: He then earned his J.D. from Stanford Law School in 1992.[7] After graduation, he worked as a judicial law clerk for Judge James Larry Edmondson of the U.S. Court of Appeals for the Eleventh Circuit, as a securities lawyer for Sullivan & Cromwell, as a speechwriter for former-U.S. Secretary of Education William Bennett, and as a derivatives trader at Credit Suisse. He founded Thiel Capital Management in 1996. He co-founded PayPal in 1999, serving as chief executive officer until its sale to eBay in 2002 for $1.5 billion.
