I'm a bit surprised that some of you don't know who Sujoy Roy is.
He is one of the founders of this site. But he is also known as the person who graduated from Cambridge University, and right after got a good job at Wallstreet. He quit his job at wallstreet when he got offered a 100.000USD sponsorship contract from Razer and became one of the first professional Quake players ever. This was somewhere around 1997-1999.
