- O’Sullivan, John Louis
- (1813–1895)The probable coiner of the expression Manifest Destiny. A lawyer, journalist, editor, and diplomat and onetime U.S. minister to Portugal, O’Sullivan used this immortal phrase in 1845, first in his United States Magazine and Democratic Review - a leading Democratic and nationalist organ - about the annexation of Texas and next in the New York Morning News about the acquisition of Oregon. O’Sullivan, who was arrested twice on account of his filibuster activity, was among other things a cultural nationalist who endeavored to promote a genuinely American literature. The discoverer and publisher of Nathaniel Hawthorne, a lifelong friend, and Walt Whitman, he also published such authors as William Cullen Bryant, Henry David Thoreau, Ralph Waldo Emerson, Edgar Allan Poe, George Bancroft, and John Greenleaf Whittier.See also <
