John Wentworth (American National Biography)
"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.
