"Long John" Wentworth, who stood 6' 6" and in his prime weighed more than 300 pounds, was the sort of colorful character that might have been created by a historical novelist seeking to portray a genial self-promoter who marched to his own drummer, yet retained the affections of the voters of Chicago and his northern Illinois district for three decades. A combative editorialist and debater who took forthright stands on the major issues of the day, Wentworth by the 1850s was a throwback to earlier times, representing a purer commitment to individual liberty and laissez faire capitalism than his businessmen enemies who thrived in the age of incorporation.
