The Nobel Prize was a prestigious award given on Earth in the 20th and 21st centuries. Its recipients included scientists such as Clifford Jones and Alistair Gryffen, as well as John Brent.
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.
