"The shot heard round the world" was a line in the famous poem "The Concord Hymn," recounting the Revolutionary War battle between the Minutemen and the British troops by a bridge in Concord, Mass. It was written by poet Ralph Waldo Emerson, who was born this day, May 25, 1803. Being friends with such notable writers as Nathaniel Hawthorne and Louisa May Alcott, Emerson composed some of the best poems in American literature. Ralph Waldo Emerson stated: "America is another name for opportunity. Our whole history appears like a last effort of divine Providence in behalf of the human race."
