Personnel: Peter Thiel at Peter Thiel (Funder) (Chairman of the Board)

NoteThe source directly confirms all three key fields of the record: (1) person = Peter Thiel, (2) org = The Thiel Foundation (referred to as 'Peter Thiel (Funder)' in the record's org field, which is an acceptable variant naming), and (3) role = Chairman of the Board. The source consistently lists Peter Thiel in this exact role across multiple years of Form 990-PF filings. The record's organization name 'Peter Thiel (Funder)' is a reasonable identifier for The Thiel Foundation, which is Peter Thiel's foundation.
