Their handle names were dmr and ken respectively. 

They were the creative driving force behind Bell 

Labs, legendary computer science operating group. 

There  contribution  to  the  hacking  world was 

creating UNIX in 1969. UNIX is an open operating 

system for minicomputers, that helped users with 

general computing, word processing and networking. 

It  soon  became a standard language.  A  program 

called Plan 9, was created as the next generation 

of UNIX, by Rob Pike. He was a colleague of Dennis 

(dmr) and Thompson (Ken).  Something  that  is not 

readily known about them is, Ritchie is the author 

of  the  C  programming  language but his favorite 

language  in  Alef.  Thompson was an amateur pilot 

and  once  traveled  to  Moscow  to  fly a MiG-29. 

Dennis  Ritchie  is  currently  the head of Lucent 

Technologies  System  Software Research Department 

and  Ken  Thompson  has extracted himself from the 

hacking world completely.
