NoteThe source directly confirms the claim. The Wikidata entry for the MacArthur Foundation (Q1424691) explicitly lists the 'inception' property as '6 January 1978', which matches the claimed founded date of 1978-01-06. The source also notes that while ROR lists 1970, the 1978 date is the authoritative one per official history, which aligns with the additional context provided. The reference is cited from the foundation's official history page.
