In a lengthy letter, Albert T. Sinclair describes his research on Celtic language and the history of the Celts in Europe during prehistoric times. Sinclair believes that Celtic influence on Europe and western Asia has been underestimated, and thinks that modern English has been influenced by Celtic far more than current scholars believe. He lists many scholars and professors he has contacted about his views, and asks if Theodore Roosevelt knows anybody who can devote time to researching the Celts more deeply.
