(1823–99), born at St. John, New Brunswick, became one of the great journalists of his time and a founder of the Republican party, to which he may have given its name. In 1855 he bought an interest in the Chicago Tribune, which he edited until his death and from 1874 controlled financially. The paper was ardently Republican, and championed Lincoln at an early date. He was elected mayor of Chicago in 1872.
