Alfred P. Sloan Foundation — Founded Date: Jan 1934

NoteThe source confirms the Alfred P. Sloan Foundation was founded in 1934, but only provides the year. The claim specifies '1934-01' (January 1934), which includes a month-level precision that the source does not provide. The source lists 'inception: 1934' with '0 references', meaning the exact month is not documented in this Wikidata entry. Since the claim is more precise than what the source confirms, this is 'partial' — the year is correct, but the specific month cannot be verified from this source.
