"Marc Ewing is the creator and originator of the Red Hat brand of software, most notably the Red Hat range of Linux operating system distributions. He was involved in the 86open project in the mid-90s."
"As a computer science student at Carnegie Mellon, Marc was known for helping other students with their computer problems. He usually wore his grandfather’s red Cornell lacrosse cap, so if you went to the lab and needed help, people would tell you, “Hey, look for the guy in the red hat, he will help you. He knows what he’s doing, he’s helpful, and he’s nice.”
He currently is involved in philanthropy.
