Carnegie Endowment for International Peace — Founded Date: 1910

Note: The source text explicitly states the Carnegie Endowment for International Peace was founded in 1910. Multiple passages confirm this: the infobox shows 'Formation December 14, 1910', the main text states 'Founded in 1910 by Andrew Carnegie', and the history section details that Andrew Carnegie announced the establishment on November 25, 1910, with the deed of gift presented on December 14, 1910. The claim matches the source exactly.
