Behind the scenes
All Nobel Prize winners explicitly named as such in Doctor Who or related fiction have been scientists. (John Brent's status as a scientist is implied, rather than explicit.) Other Nobel laureates, such as Barack Obama, have appeared, but their status as Nobel Prize winners has not been mentioned.
