Claude Gernade Bowers (1878-1958), American journalist, historian and diplomat, ambassador to Spain 1933-39. The Spanish Civil War (1936-39) took place during his time in office. He was the author of Beveridge and the Progressive Party and Jefferson and Hamilton.
As author of Jefferson and Hamilton Bowers was one of the few modern historians in good odour with Pound, who often recommended the book as a true account of the struggle between Jefferson and Hamilton. ...[Pound] was surprised to learn that [Bowers] was United States ambassador to Spain. Bower's letter was dated 10 May 1938, from San Jean de Luz in France; in it he referred to 'the atmosphere of incredible hate' in Spain, a phrase which Pound later worked into his cantos.
