Nobel Prize

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)

According to one account, Sarah Jane Smith, then using the name Sarah Jane Morley, addressed the Nobel Academy in 1998. (NA: Christmas on a Rational Planet)

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.
