The Watson and Crick icon is a really well construction and coloured icon but yeah I can't see past those two jerks being in it hahaha.
I think the problem with iconning is that sometimes the people you want to make icons of don't always result in good quality icons (main reason I don't icon Neil DeGrasse Tyson for every since icontest, I've tried so many times and failed!). You totally make up for missing Franklin though with the Charles Darwin icons, that man is my hero *is a nerd for his soil studies*
