Andrew Johnson gives truth to the saying that in America, anyone can grow up to become President. Born in a log cabin in North Carolina to nearly illiterate parents, Andrew Johnson did not master the basics of reading, grammar, or math until he met his wife at the age of seventeen. The only other man to attain the office of President with so little formal education was Abraham Lincoln. Whereas Lincoln is esteemed as America's greatest President, Johnson, his successor, is ranked as one of the worst.
