John D. MacArthur @ MacArthur Foundation
The Wikidata source explicitly lists 'John D. MacArthur' under the 'founded by' property. The claim states that the MacArthur Foundation's founder is 'John D. MacArthur', which directly matches the source text. Note that the foundation was also founded by Catherine T. MacArthur (listed as a co-founder), but the claim is not contradicted by this—it is simply incomplete. The source confirms John D. MacArthur as one of the founders.
