"Let's begin with the fact that I'm angry. I'm angry because my invention has never carried my name and because of this, I never get the credit. My invention revolutionized a generation and to this day, most people call my invention by what the process was originally called, even if the company which held the patent doesn't make the machine! To add insult to injury, I took my invention to IBM and the US Army Corps of Engineers and it was rejected! Today, most people just take it for granted but without me, businesses would probably be still in the dark ages and what can now be done in a matter of seconds, would take days."
"Who am I"?
"What is the invention?"
100 kudos if both questions are correctly answered!
