Nobel Prize
From Tardis Wiki, the free Doctor Who reference
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. (DW: The Green Death, K9TV: The Custodians, TN: Time and Relative)
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.
