The Bank of England has released a list of scientists who have been nominated to feature on the new £50 note.
The list includes computing pioneers Alan Turing and Ada Lovelace, telephone inventor Alexander Graham Bell and astronomer Patrick Moore.
The Bank said it had received a total of 174,112 nominations, of which 114,000 met the criteria.
To be on the list, the individual must be real, deceased and have contributed to the field of science in the UK.
The list, which includes more than 600 men and almost 200 women, includes black holes expert Stephen Hawking, penicillin discoverer Alexander Fleming, father of modern epidemiology John Snow, naturalist and zookeeper Gerald Durrell, and British-Jamaican business woman and nursing pioneer Mary Seacole.
Further names will be considered up until nominations close on 14 December.
After that the decision will be considered by the Bank’s Banknote Character Advisory Committee.
Nominations can include anyone who worked in any field of science including astronomy, biology, bio-technology, chemistry, engineering, mathematics, medical research, physics, technology or zoology.
There are currently 330 million £50 notes in circulation, with a combined value of £16.5bn, the Bank said.
