From John Morton, Pontypridd, Mid Glamorgan, UK
I agree with Alice Bell's support for Dorothy Hodgkin to be on the new UK £50 note (10 November, p 24). Another aspect of her career is that she attended a state school, whereas each of the other 20th-century candidates mentioned – Rosalind Franklin, Alan Turing and Stephen Hawking – went to private schools. Mentioning this could show children in state schools that they have as much chance of getting on in science as anyone else – I hope.
