"Go West Young Man, Go West"
"Horace Greeley is usually attributed with originating the remark, 'Go west, young man, go west.' , however, Greeley did not first use this expression. His role was simply to reprint in an 1851 edition of his New York Tribune an article by John L. Soule in which Soule wrote, 'Go west, young man, and grow up with the country.'
The expression caught on with the public and, because it first appeared in Greeley's newspaper, it became popularly associated with him. Despite repeated attempts by Greeley to disclaim credit for the remark, most people still believe he originated it."
