Abraham Lincoln

Abraham Lincoln was the sixteenth President of the United States.

Biography
In 1863, the Third Doctor gave to President Lincoln a sketched map he had made of the Confederate lines at Gettysburg. Lincoln gave the map to General Grant, thus helping the Union Army to win the Battle of Gettysburg. (TVA: Backtime)

On 19 November of that year, Lincoln delivered his Gettysburg Address. The First Doctor, Ian Chesterton, Barbara Wright and Vicki watched the speech on the Time-Space Visualiser. (DW: The Chase)

On 5 April 1865, the Fifth Doctor saved Lincoln from an assassination attempt in Richmond, Virginia. (TN: Blood and Hope)

Iris Wildthyme once shared breakfast with Lincoln on the White House lawn after saving the United States from "Martian invaders" for the third time. She told George Strangeways that they had had "such a laugh." (IW: The Panda Invasion)

The Eighth Doctor once claimed that he — or an earlier incarnation — had warned Lincoln not to go to Ford's Theatre, where the president would be shot. (BFA: Minuet in Hell)

Behind the scenes

 * Abraham Lincoln is one of only three real-world US Presidents to be portrayed on-screen in televised Doctor Who, not counting the wax dummies from Spearhead from Space. The others are Barack Obama, who appeared in The End of Time, and Richard Nixon, who appeared in The Impossible Astronaut/Day of the Moon.
 * Backtime has its history a bit wrong. In reality, Grant was actually in the west, running the Union forces at the Battle of Vicksburg at the time that Gettysburg was being fought.
