Oliver Morgenstern (Donna's World)

Oliver Morgenstern had his life changed for the worse on 25 June 2007, when Donna Noble turned right instead of left; this small change in affairs produced Donna's World.

Morgenstern was a medical student at Royal Hope Hospital when it was transported to the Moon. Upon the hospital's return, he was the only survivor. (TV: Turn Left)

While on the Moon, the hospital was invaded by the Judoon. (TV: Turn Left, Smith and Jones) A woman - Sarah Jane Smith - took control of the situation. With the hospital running out of oxygen, Morgenstern was given the last oxygen tank by one of his colleagues, Martha Jones.

Upon his return to Earth as the only survivor, Morgenstern was interviewed by BBC News. (TV: Turn Left)
