John A. "Black Jack" Logan, Civil War general and founder of Memorial Day.
From Abraham Lincoln's Gettysburg Address: "...from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion -- that we here highly resolve that these dead shall not have died in vain -- that this nation, under God, shall have a new birth of freedom -- and that government of the people, by the people, for the people, shall not perish from the earth."
