How He Chooses His Subjects
"I realize there are a lot of scientists that I’ve missed! I did make a few rules for whom I’d include in this selection, which are: the scientist must have been alive at some point in the 20th century. This is a practical consideration, as it really narrows the field down, and it eliminates a lot of the more outrageously-dressed characters, allowing me to work with mostly dudes in suits. No scientists famous for major medical breakthroughs. Primarily because medical heroes is a category all its own, and there are hundreds to choose from. I’ve included Alexander Fleming here, because he was primarily a chemist, and because his discovery of penicillin was not a discovery made in the course of trying to cure something."
