Fernando Corbato (yeah, I’ve never heard of him either) passed away recently at the age of 93. Fernando was instrumental in modernizing computing. You see, back in the day, even before I started getting interested in computers, people didn’t have a machine on their desks, much less in their pockets. They probably didn’t have a computer anywhere in the office. If a company had one at all, it was down in the basement manned by some white shirted guy with a black skinny tie, glasses, and a pocket protector.
Computing – The Way It Used To Be
Programs were recorded on punch cards, which were punched by keypunch clerks and stacked in a certain order. They were delivered to the programmer, who would run that program after the others in front of it had finished. I know that sounds like the Flintstones, but like today, that was the most advanced system people had.
Then along came Fernando (“Corby” as he was called). In 1961 Corby, a professor at MIT, demonstrated a Compatible Time Sharing System (CTSS) which enabled a computer to be accessed by more than one person at a time. Programs could be stored on tape, and one person could be debugging a program while another was executing theirs. This is something we all take for granted these days. This also meant that a computer could be accessed via a teletype style terminal from another part of the building, or like in the case of the terminal in my high school, from across town. All was good.
Corby To The Rescue?
So what is the issue? What did Corby do that causes us so much pain these days? Well, in order for a computer to be accessed by multiple people at the same time, the machine needed to know who was who. And also one person’s program needed to be protected from other people, lest they get in there and mess something up. So Fernando “Corby” Corbato invented the login and password. (Boo, hiss). Yep, the fact that we have to rely on a password manager (or a slew of sticky notes on the desk) in order for us to be able to keep up with how we log in can all be blamed on Corby. Thanks, dude.
