Department 1127 was the place of invention of the AT&T dialect of Unix, created by Thompson and Ritchie is 1969 whilst they spent time reviewing their recent experiences of Multics. Unix was written in PDP assembler and later ported to C after Dennis Ritchie created it from B, which was itself created from BCPL (This is a simplistic history!).
It is a sad demise when such a great place of creation has closed. This department was the place of work for many greats in the computer industry.
What has this to do with Oracle Security? - well nothing specifically except a large number of Oracle installations run on systems derived from work these guys did originally a long time ago.
