Henry Raper
Henry Raper was a man who lived a long time ago. He was a scientist who studied stars and planets in the sky. He used special tools called telescopes to look at the stars and see what they were made of.
One thing that Henry Raper was really good at was making maps of the stars. He would draw pictures of the sky and mark where all the stars were so that other people could use them to study too.
Even though he lived a long time ago and didn't have fancy computers or cameras like we do now, Henry Raper was still very important to science. His maps helped scientists understand a lot more about the stars and the universe.
