Joshua Naismith
From Tardis Wiki, the free Doctor Who reference
Joshua Naismith owned the Immortality Gate. He captured the Master and made him open it. He wanted to use it to make his daughter Abigail immortal. Instead, the Master used it to turn everyone in the world into a copy of himself-including Naismith. ((DW: The End of Time)
He also wrote the book Fighting the Future.
