[Heber C. Kimball]
His brusque, undiplomatic, and unsophisticated ways were no longer in style as Utah became increasingly less isolated from mainstream American life. He lived long enough to endure what he considered to be a maneuvering to reduce his influence. He died on 21 June 1868 from a subdural hematoma occasioned by being thrown from his wagon by a lunging horse.
