Teachers and parents: you have my authorization to print these images (in full-color or black-and-white) as a poster for your classroom, your kid’s bedroom, your office, your t-shirt or wherever you want, for free. Please don’t sell it or use it on products intended for sale. The high-res images are available here and here.
I am aware that many important scientists are missing from these illustrations. The selection process was hard! Please feel free to suggest your favorite famous scientists in the comments below. You can even create your own poster. These are far from complete; just my little personal attempts at inspiring young girls to study science.
