Cornelius Ambrosius Logan (born Baltimore, Maryland, May 4, 1806; died on the Ohio River near Wheeling, then in the state of Virginia, February 22, 1853) was an American actor, playwright, and journalist who was father to a famous family of actresses and writers.
Born in America to Irish immigrant parents, Logan was educated for the Catholic priesthood at St.
Mary's Seminary in Baltimore, but then entered a shipping house, where his work led him to travel to Europe several times.
He next became a journalist, and after working as a drama critic began to write plays and act himself.
He moved to Cincinnati with his growing family in 1840 where he operated the "National Theater".
He later operated theaters in other cities and traveled with his oldest daughter Eliza, playing comic "yankee" roles.
He also wrote short stories, poetry, notably a well-regarded Ode to the Mississippi, and a defence of the theater against criticism from the pulpit.
