The stats to date of people who have been featured on the £5 note (except the Queen, who is exempt because didn't get there on merit) are 15 men : 2 women. Caroline Criado-Perez is running a social media campaign (#banknote) through her website The Women's Room to try and prevent the Bank of England making it 16 : 2.
Why does it matter? Because it will mean that no English banknote will have a female face on it despite women representing half the population. And if no-one says anything then it's another patriarchal footprint on history; not all the significant figures from the past are white and male.
My vote is for Rosalind Franklin, for her vital research into the discovery of DNA, read her galling wiki page here. My hall of residence at university (KCL) was named after her and on my first day I remember looking up at the name and thinking: "Who's she?" If she'd been on a banknote perhaps I'd have been more clued-up.

The Independent on Sunday ran some good alternative fiver graphics on this story over the weekend. Although technically the face needs to be of someone who is dead, in the future why not the artist Bridget Riley or fashion legend Vivienne Westwood.
