When I wrote my book The Science and Technology of Leonardo da Vinci, one of the things that really captivated me was how Leonardo learned a lot from an early scholar and scientist, Alhazen. I’d never heard of Alhazen before, but he did a lot of exciting work. 
It turns out Alhazen is the Latinized version of his real name, Ḥasan Ibn al-Haytham. He’s was a polymath and studied optics. He was a leader during the Islamic Golden Age. There are some books about him, and he wrote books himself. But the world could always use more books and I hope someone writes a book for kids exploring how Hasan Ibn al-Haytham saw the world.
Take a look at this Wikipedia page about him and explore the primary and secondary sources at the bottom of the entry to find further reading!
