Frederick John Horniman was a man who lived a long time ago and he loved collecting things from all over the world. He had a big house and he used to fill it with all the things he collected.
He collected things like beautiful art, interesting bugs, shiny shells, and even funny-looking animals. He kept all of these things in his house and people loved to come and see all the things he had collected.
Eventually, he decided to open up his house to the public so that everyone could come and see all the things he had collected. He even made sure that children could come and learn about all the amazing things in the world by making his museum a fun and interactive place.
That's why we remember Frederick John Horniman today - because he loved collecting things from all over the world and he wanted to share them with everyone.
