ELI5: Explain Like I'm 5

Carl Schenck

Carl Schenck was a man who lived a long time ago and he really liked to study things. One of the things he studied was how to make machines that could sort out different kinds of things. You know how sometimes you want to pick all the green M&Ms out of a bowl of mixed candies? Well, imagine trying to do that with really tiny M&Ms that are all jumbled up together. That's really hard to do! But Carl Schenck figured out how to build a machine that could quickly and easily sort things like that.

People liked Carl Schenck's sorting machines so much that they started using them in factories all over the world. That meant that more things could be made faster and more efficiently. Carl Schenck was so good at making these machines that he even became famous for it!
