Wallace John Eckert was a very smart man who lived a long time ago. He was born in April 19, 1902 in a place called Pittsburgh. When he grew up, he studied a lot and became really good at math and science. He loved working with computers and was one of the first people to ever use them!
Back then, computers were really big and took up a whole room. They weren't like the ones we have today that are small enough to fit in your pocket. Wallace John Eckert wanted to use computers to help solve problems and do really cool things.
One thing that Wallace John Eckert did was help build some of the very first computers. He also used computers to help with things like predicting weather patterns and keeping track of important information.
Even though computers have changed a lot since Wallace John Eckert was around, he helped make them what they are today. So we can thank him for all the amazing technology we have now!
