Edsger W. Dijkstra was a Dutch computer scientist and mathematician who was famous for inventing things called algorithms. Algorithms are like recipes for computers - they give computers a set of step-by-step instructions to solve problems like finding the best way to get from one place to another. They can also help computers sort through large amounts of data quickly. Edsger W. Dijkstra was a genius who helped invent many of the algorithms that we use today. He made the world of computing much smarter and faster!
