     Theodore Roosevelt, "Citizenship in a republic," address delivered at the Sorbonne, Paris, April 23, 1910, African and European addresses (New York & London:  G. P. Putnams's Sons, The Knickerbocker Press, 1910), 39 ("know") | Presidential addresses and state papers and European addresses, [vol. 8,] December 8, 1908, to June 7, 1910, Homeward bound edition (New York:  The Review of Reviews Company, 1910),  2191 (cumulative) ("knew").  Given the discrepancy (I haven't looked for others), could he have delivered this in French?
