Turtledove Appearances:

Joseph "Joe" Noggle is an important supporting character in L. Sprague de Camp's 1940 short work, "The Wheels of If". He is a doctor from the Bretwaldate of Vinland who is hired by a racialist political faction to disrupt Bishop Ib Scoglund's campaign for Skrelling civil rights. He finds a way to disrupt Scoglund's "wheel of time," causing Scoglund's mind to be interchanged with the minds of Scoglund's various analogs in other timelines, including Allister Park, a man from OTL. In the process, Noggle disrupts his own "wheel", resulting in his own multiple personality disorder, which causes him to be committed to an insane asylum.

He is only briefly referenced in Harry Turtledove's "The Pugnacious Peacemaker", a sequel to de Camp's work.
