Enclosed in a letter, written in September 1815 by William David Lewis (1792-1881) to the United States minister in Sweden, Jonathan Russell (1771-1832), is an interesting and unique example of an American's effort to compose verse in the Russian language. Though only a curiosity of Russian literature, “Yankee Doodle” illustrates the degree of facility gained by one of the first American students of Russian after more than a year of study. Of additional interest is the pronunciation guide which Lewis furnished Russell—rare evidence on how Russian was actually spoken in the early nineteenth century.
